    Liquid crystal display {LIQUID CRYSTAL DISPLAY DEVICE}
    [15] The present invention relates to a liquid crystal display device, and more particularly, to a liquid crystal display device capable of minimizing the overall size of the liquid crystal display device by improving the coupling structure between the liquid crystal display module and the back case.
    [16] Recently, information processing devices have been rapidly developed to have various forms and functions, and faster information processing speed. The information processed in such an information processing apparatus usually has an electrical signal form. In addition, the information processing apparatus needs a display apparatus that serves as an interface for allowing a user to visually check the processed information in the information processing apparatus.
    [17] On the other hand, among the display devices as described above, in recent years, the liquid crystal display device has been developed, which is lighter and smaller than the typical CRT display device and has excellent functions such as full-color and high resolution. As a result, the liquid crystal display device has been widely used as a display device of computer monitors, home wall-mounted televisions, and other information processing devices, which are representative information processing devices.
    [18] The liquid crystal display converts optical properties such as birefringence, photoreactivity, dichroism, and light scattering characteristics of a liquid crystal cell that emits light by applying a voltage to a specific molecular array of the liquid crystal and converts it into another molecular array. It is a display using the modulation of the light by a liquid crystal cell by converting into.
    [19] In addition, the liquid crystal display device is largely divided into twisted nematic (TN) and super-twisted nematic (STN) methods, and an active matrix display method using a switching element and a TN liquid crystal and an STN liquid crystal using a difference in driving method. There is a passive matrix display method.
    [20] The main difference between the two methods is that the active matrix display method is used for TFT-LCD, which drives the LCD using the TFT as a switch, and the passive matrix display method does not use transistors. I don't need it.
    [21] In addition, according to the method of using the light source, it may be classified into two types, a transmissive liquid crystal display device using a backlight and a reflective liquid crystal display device using an external light source.
    [22] In the transmissive liquid crystal display device using the backlight as a light source, the weight and volume of the liquid crystal display device are increased by the backlight, but are widely used because they have a display function independently without using an external light source.
    [23] 1 is an exploded perspective view schematically showing the configuration of a conventional liquid crystal display device.
    [24] Referring to FIG. 1, the liquid crystal display device 100 includes a liquid crystal display module 80 and a back case 90 for accommodating the liquid crystal display module 80.

It is turned off and outputs an electrical signal necessary for pixel formation to the drain terminal.
    [30] The color filter substrate 52b is provided to face the thin film transistor substrate 52a. The color filter substrate 52b is a substrate in which RGB pixels, which are color pixels in which a predetermined color is expressed while light passes, are formed by a thin film process. In addition, a common electrode made of indium tin oxide is coated on the entire surface of the color filter substrate 52b.
    [31] When power is applied to the gate terminal and the source terminal of the thin film transistor of the thin film transistor substrate 52a and the thin film transistor is turned on, an electric field is formed between the pixel electrode and the common electrode of the color filter substrate 52b. The arrangement angle of the liquid crystal injected between the thin film transistor substrate 52a and the color filter substrate 52b is changed by the electric field thus formed, and the light transmittance is changed according to the changed arrangement angle to obtain a desired pixel.
    [32] A driving signal and a timing signal are applied to the gate line and the data line of the thin film transistor in order to control the arrangement angle of the liquid crystals of the liquid crystal display panel 52 and the timing when the liquid crystals are arranged.

Is connected to the carrier package 56.
    [35] The integrated printed circuit board 54 receives a video signal generated from an external information processing device such as a computer, and provides a source unit for providing a data driving signal to the liquid crystal display panel 52, and the liquid crystal display panel 52. A gate portion for providing a gate driving signal is formed in the gate line of the gate line.
    [36] That is, the integrated printed circuit board 54 generates a gate driving signal, a data signal for driving a liquid crystal display, a plurality of timing signals for applying these signals at an appropriate time.
    [37] Here, the gate driving signal is applied to the gate line of the liquid crystal display panel 52 through the gate side flexible circuit board 58, and the data signal is transferred to the liquid crystal display panel 52 through the data tape carry package 56. Applied to the data line.

    [40] An upper portion of the light guide plate 43 is provided with an optical sheet 45 for uniforming the brightness of light emitted from the light guide plate 43 and directed to the liquid crystal display panel 52. In addition, the lower portion of the light guide plate 43 is provided with a reflector plate 44 which reflects the light leaked from the light guide plate 43 back to the light guide plate 43 to increase the efficiency of the light.
    [41] The display unit 20 and the backlight unit 40 are accommodated in the mold frame 60 and fixed. The mold frame 60 has a box shape of a rectangular parallelepiped and an upper surface thereof is opened. That is, it is composed of four side walls and the bottom surface, the bottom surface is formed with openings for bending the integrated printed circuit board 54 to be bent along the outer surface of the mold frame 60.
    [42] Meanwhile, the top chassis 50 has a rectangular parallelepiped shape like the mold frame 60, and an upper surface portion thereof is opened to expose the liquid crystal display panel 52, and a sidewall portion is bent in an inner vertical direction so as to expose the liquid crystal display panel.

    [43] FIG. 2 is a perspective view illustrating a coupling structure of the liquid crystal display module 80 and the back case 90 in the liquid crystal display device 100 shown in FIG. 1.
    [44] Referring to FIG. 2, the top chassis 50 is integrally formed with a plurality of protrusions 70 for coupling the top chassis 50 to the back case 90 on opposite sides of the top chassis 50. In the center of the 70, a fastening hole 72 having a predetermined diameter is formed.

By being mutually coupled, it is firmly fixed on the inner bottom surface of the bag case 90.
    [47] However, the conventional liquid crystal display 100 having the above-described structure is formed by combining the protrusions 70 having a predetermined width W on both sides of the top chassis 50, thereby combining the top chassis 50. There was a problem that the size of the back case 90 is increased by the width (W) of the protruding portion 70 extending to the outside. As a result, the overall size of the liquid crystal display device 100 increases, which causes a problem contrary to the trend of the current liquid crystal display device, which is gradually lighter and smaller.
    [48] Accordingly, an object of the present invention is to provide a liquid crystal display device which can minimize the size of the liquid crystal display device by improving the coupling structure of the liquid crystal display module and the back case. .
