- the first side 4 0 a and the fourth side 4 0 d opposite to the first side 4 0 a are normally swallowed by a sash or the like. Therefore, it is preferable to reciprocate any of the conductors 15 and 16 along the first side 40 a and the fourth side 40 d from the viewpoint of design.
- the method of manufacturing the EL display panel 40 according to the present embodiment is the same as the method of manufacturing the EL display panel 10 described above, and thus the description thereof is omitted.
- the surface light emitter 4 1 of the present embodiment since the intermediate films 3 a and 3 b cover the conductive wires 15 and 16 over a predetermined length, the conductive wires 15 and 16 and the intermediate wires It is possible to prevent the infiltration of moisture transmitted along the interface between the films 3a and 3b, and to prevent the occurrence of the deterioration of the organic EL laminated film 7 for a long time more reliably.
- the EVA in the form of sol is crushed by heat when the intermediate films 3 a and 3 b are melted by heat, and surplus EVA is obtained.
- another intermediate film made of EVA may be arranged in advance in the peripheral part of the organic EL laminate 1.
- the area from the sheet of EVA is larger than the area of the organic EL laminate 1 and the intermediate sheet is Cut out the films 17 a., 17 b and stack the intermediate film 17 b, the organic EL stack 1 and the intermediate film 17 a in this order from the lower side of the figure (FIG.
- the two other intermediate films 18 a and 18 b cut from the sheet of EVA having a thickness substantially the same as the thickness of the organic EL laminate 1 at the peripheral portion of the laminate 1 are the organic EL They are placed on both sides of the laminate 1, respectively, and they are held by two glass plates 2a and 2b from the upper and lower directions in the figure (FIG. 6B). Then, the organic EL laminate 1 sandwiched between the flat glass 2 a and 2 b, the intermediate film 17 a and 17 b and the other intermediate films 18 a and 18 b are heated and cooled to form the intermediate film 1. 7a, 17b and the other interlayers 18a, 18b are melted and solidified to adhere to each other (FIG. 6C). Thereby, the generation of a gap can be reliably prevented at the peripheral portion of the organic EL stack 1, and the generation of the deterioration of the organic EL stack 1 in the long term can be more reliably prevented. Can.
- the sheet glass 2a, 2b is an EL display. Since it functions as a member for defining the shape of the panel, in the use of the surface light emitter, it is not always necessary that the both sides be covered with the sheet glass 2 a, 2 b or the like. Also in this case, in the surface light emitter, both surfaces and the peripheral portion of the organic EL laminate 1 are covered with the intermediate films 3a and 3b, so that the same effects as the above-described effects can be obtained. Further, in the surface light emitters according to the first and second embodiments described above, a thermoplastic resin such as EVA is used as the material of the interlayers 3a and 3b. A thermosetting resin may be used.
- the transparent substrate for covering the surface light emitter according to the first and second embodiments described above is not limited to the flat glass 2 a and 2 b made of non-alkaline glass, but may be low alkaline glass, alkali It is possible to use soda lime glass or quartz glass which has been treated to prevent elution.
- the material of the substrate is not only glass, but resin or metal materials may be used.
- the resin ABS (Acrylo nitrile Butadiene Styrene) resin or acrylic resin is used. This is preferable, and Al, Cu, and Fe are preferably used as the metal material, and in addition, SUS, ceramic, Pi, and Au are used. May be.
- the substrate is disposed so as to face only the surface opposite to the light emitting surface of the organic EL laminate 1.
- the organic EL laminated film 7 has a passive structure, but may have an active structure.
- the organic EL laminate 1 is Although it is assumed that the system has a puemie structure, it may have a bottom ememi- sion structure.
- the EL laminated film may be an inorganic EL laminated film instead of the organic EL laminated film 7.
- one comprising an insulating layer, a light emitting layer, and an insulating layer, and one comprising an electron barrier layer, a light emitting layer, and a current limiting layer are used sequentially from the lower transparent conductive film 6 side.
- the configuration of the present invention can be applied not only to the EL display panel 10 but also to a CRT, a PDP (Plasma Display Panel) and a liquid crystal display panel, and the lower transparent conductive film 6 and the upper transparent conductive Structures are arranged between the membranes 8 according to their respective configurations.
- the surface light emitter of the present invention since the planar light emitting portion using the organic material and the covering portion covering the both sides and the peripheral portion of the light emitting portion are provided, the light emitting portion is covered with the covering portion in manufacturing. As well as being easy to manufacture, since there is no space in contact with the light emitting part, it is possible to prevent the occurrence of long-term deterioration of the light emitting part.
- the covering portion is preferably made of a thermoplastic resin, and both sides and the peripheral portion of the light emitting portion can be covered easily and surely by melting and solidification of the thermoplastic resin. As a result, it can be manufactured more easily, and long-term deterioration of the light emitting part can be surely prevented.
- the transparent substrate cover the covering portion, and it is possible to surely block the intrusion of moisture through the covering portion to the light emitting portion, and in the long run It is possible to more reliably prevent the occurrence of deterioration of the light emitting unit.
- the light emitting part has an electrode and a lead connected to the electrode, and the covering part covers the lead over a predetermined length, In addition, it is possible to prevent the penetration of moisture that travels through the interface of the coating, and thus to prevent the occurrence of the deterioration of the light emitting part in the long term more reliably.
- the light emitting portion can be touched. Since there is no space, it is possible to prevent the occurrence of long-term deterioration of the light emitting part.
- two film-like materials which are made of a covering material and whose area is larger than the area of the light emitting portion, are combined with the light emitting portion interposed between them. Since the film-like material is adhered at the portion where the light emitting portion does not intervene, the peripheral portion of the light emitting portion can be covered with certainty, and the occurrence of the deterioration of the light emitting portion can be reliably prevented.
- a surface light emitter of the present invention it is preferable to combine two film substances with another film substance at the part where the light emission part does not intervene, and the periphery of the light emission part It is possible to reliably prevent the occurrence of a gap in the part, and thus to prevent the occurrence of the deterioration of the light emitting part in the long term more reliably.
