ABSTRACT:
An organic EL display device includes a moisture-resistant structural body which covers an upper surface and a side surface of an organic light emitting layer which is formed on a main surface of an insulation substrate and is formed by stacking a first moisture prevention layer, a moisture absorption layer, a second moisture prevention layer, and an adhesive layer which covers the upper and side surface of the organic EL layer. The first moisture prevention layer, the moisture absorption layer and the second moisture prevention layer on the side surface of the organic light emitting layer include portions are bent toward the side surface from the upper surface of the organic light emitting layer and, further, are bent parallel to a main surface of the insulation substrate from the side surface, and lower surfaces of the respective bent portions of at least one of the layers are hermetically adhered to the main surface of the substrate by the adhesive layer.
