Patent ID: 7898174

Claim:
An organic EL display device comprising: a first electrode which is formed on a main surface of an insulation substrate; an organic EL layer of the multi-layered structure which is formed on the first electrode; a second electrode which is formed on the organic EL layer; and a sealing member which covers the second electrode and has a peripheral end portion thereof sealed to a peripheral portion of the insulation substrate; wherein the organic EL display device includes a moisture-resistant structural body which covers an upper surface and a side surface of the organic EL layer and is formed by stacking over the organic EL layer, at least a first moisture prevention layer, a moisture absorption layer and a second moisture prevention layer in this order; wherein the moisture-resistant structural body includes at least one adhesive layer which covers the upper surface and the side surface of the organic EL layer; wherein the first moisture prevention layer, the moisture absorption layer and the second moisture prevention layer have portions which are bent toward the side surface from the upper surface of the organic EL layer and, further, are bent parallel to the main surface of the insulation substrate from the side surface, and a lower surface of one of the bent portions of at least one of the first moisture prevention layer, the second moisture prevention layer and the moisture absorption layer is hermetically adhered to the main surface of the insulation substrate by the at least one adhesive layer; and wherein the at least one adhesive layer is at least formed between the moisture absorption layer and the second moisture prevention layer, and the first moisture prevention layer and the moisture absorption layer are fixedly mounted on the main surface of the substrate by the at least one adhesive layer together with the second moisture prevention layer.
