Abstract:
An organic EL display device includes lower electrodes each provided for each of pixels, a bank layer formed so as to cover the peripheries of the lower electrodes and including bank openings through each of which a portion of the lower electrode is exposed, a light-emitting layer, an organic layer including portions each formed in the bank opening, a first barrier layer covering the organic layer, a second barrier layer covering the first barrier layer, an intermediate layer located at the edges of the bank openings, and light reflection films each provided under the lower electrode for each of the pixels. A first region where the intermediate layer is present when the pixel is viewed in a plan view includes, above or under the intermediate layer, a different layer structure from that of a second region inside the first region.
