ABSTRACT:
An organic electroluminescence display device is provided that prevents a desiccant from being deteriorated. This organic electroluminescence display device has a superior moisture resistance and forms a high barrier against moisture and oxygen while still keeping the display low profile and lightweight. The organic electroluminescence display includes a laminated material and, across this laminated material, a first flexible substrate and a second flexible substrate. The laminated material is composed of layers, with different conductivities, that constitute an electronic circuit that includes a pair of electrodes across a light-emitting layer. At least one of the first flexible substrate and the second flexible substrate includes a desiccant. The flexible substrate that includes this desiccant includes a metal foil that is a base material on which the desiccant is formed. The desiccant is composed of a plurality of island-like desiccant pieces each separated from other desiccant pieces.
