    Disclosed herein is an electroluminescence structure comprising, in sandwich arrangement, a transparent substrate made of, e.g., glass, a first transparent electrode layer, a luminescence layer, a number of second transparant electrode layers disposed at least partially on the luminescence layer, and a black layer arranged in contact with the luminescence layer and the second electrode layer. The black layer covers the second electrode layer and is in contact with the luminescence layer outside of said second electrode layers. The black layer consists of an insulating layer and a wiring disposed on said insulating layer. Openings reaching the second elctrode layer are defined in the insulating layer opposite said second electrode layers such that the wiring can make electrical contact with the second electrode layers through the openings.

    The invention relates to electroluminescent devices and may be used for the manufacture of plectroluminescent displays.
    The aim of the invention is to extend the overall service life of the device by positioning the light-absorbing black layer so that it is not exposed to the electric field of the electrodes and is in contact with the luminescent layer, the second electrode layer being made transparent
    Figure 1-3 shows a schematic representation of the proposed device, the incision (options).
    The device (figure 1) contains a transparent base 1, made, for example, of glass, on which is located the first electrode layer 2, which is also transparent. The luminescent layer 3, 3, 3, known in the art, is located on the first transparent electrode layer 2. Several adjacent electrode layers 4 are located on said luminescent layer 3,
    3, 3 in accordance with the required configuration. Layers 2, 3, 3, 3 and
    4 can be obtained by using the Scientific Research Institute of thin-film technology, for example, the so-called Atomic Layer Epitaxy (AIjE). The light-absorbing black insulating layer 5 coats the second electrodes 4 and contacts the luminescent layer 3 outside the said electrodes 4.
    The device shown in Fig. 1 is used when all necessary conductors are to be led out to the edges of the component for connection. This may be when, for example, the matrices have a relatively low definition.
    The device according to figure 2 differs from the device in figure 1 in that the black layer (light absorbing or layer having light different from black) consists on one side of the insulating layer 5 covering the second electrode layer 4 and in contact with the luminescent layer 3 , 3 s outside the specified second layer 4, and on the other hand from the electrical wiring diagram 6 located on the specified insulating layer
    5 and implemented using the use of film or thick-film technology.

    Against each of the second: electrodes 4 in the black layer 5 is made about the m-hole, which includes the specified one. the second electrode 4. Protrusions 7, which serve to electrically connect the installation circuit 6 with the required electrodes 4, retract from the electrical wiring circuit 6. The protrusion 7 can be fulfilled, for example, when printing a black conductive zone, completely cutting hole 8.
    In high-definition materials, the conductivity of the upper electrode becomes more critical. In such a case, the design variant shown in FIG. 2 is used. The design allows the separation of a separate electrical element (for example, element 4 in Fig. 2), as well as the use of thinner conductive strips, for example, to connect several seven-segment elements so that the corresponding segments are electrically connected.
    If the electrical wiring diagram is completely made of black material, then separate conductive zones 7 are not required. Device coherently FIG. 3 is a preferred design option in reproducing devices with relatively low definition, where the configuration of the electrodes requires separations. For example, a seven-segment element may contact so that the central segment contacts at the top, for example, the top or bottom electrode.
    The black insulating thick-film layer 5 of the structure shown in FIG. 1 can be made of any light-absorbing thick-film material or it can be made using thin-film technology, for example, from A120z / A1 alloy, mouse sulphide or mouse selenide. Such layers can be made using known methods for producing a thick or thin film.
    Layer 5 in Figures 1, 2 and 3 is an insulating polymer film containing a known black. pigment. One suitable material for this is a paste suitable for drying, developed by electronic science laboratories, available to produce.
    3P
    Layer 6 in FIG. 2 is a known conductive polymer film coated with metal. One of the materials suitable for this purpose is the one-component material produced using silver, which can be printed on, and this material has been developed by scientific laboratories in electronics. The conductive zones 7 in FIG. 2 and the layer 6 in FIG. 3 are known carbon-coated conductive polymer films; One of the suitable materials for this purpose is a paste suitable for drying, suitable for drying, developed by scientific laboratories in electronics. Electrical wiring diagram 6 can be performed, for example, by applying aluminum. In this case, both electrode layers 2 and A are transparent. They can be, for example, ITO (indium - tin, oxide) layers metallized by pressing.
    The luminescent layer 3, C, consists of a known laminated structure containing a light-emitting layer 3, usually a layer of ZnS; Mn, and auxiliary layers 3 and 3, which restrict the flow of current, which are made of metal oxide.
