Patent ID: 8895974

Claim:
An organic EL display device comprising an organic EL substrate having a plurality of light emission regions arranged in a matrix, and a sealing substrate, the organic EL substrate and the sealing substrate facing each other, and having a frame-like non-display region provided at a circumferential portion of the substrates, and a display region provided on an inner side of the frame-like non-display region, wherein the organic EL substrate includes an organic EL substrate body, a plurality of switching elements provided on the organic EL substrate body, each corresponding to one of the plurality of light emission regions, an insulating layer covering the organic EL substrate body and the plurality of switching elements and having a flat surface, a plurality of lower electrodes of a light transmissive material provided on the insulating layer, each corresponding to one of the plurality of light emission regions, a separation wall portion of a light transmissive material provided on the insulating layer, corresponding to a region other than the light emission regions, and configured to separate the plurality of light emission regions from each other, a plurality of organic EL layers each covering a corresponding one of the plurality of lower electrodes, and an upper electrode of a light reflective material covering the plurality of organic EL layers, and light generated in the organic EL layers is propagated to the organic EL substrate body to be viewed as an image on the organic EL substrate, the insulating layer includes a first insulating film and a second insulating film provided thereabove, there are a plurality of the upper electrodes each covering a corresponding one of the plurality of organic EL layers, and a reflection film is provided between the first and second insulating films, corresponding to the region other than the light emission regions, and is configured to reflect toward the sealing substrate a portion of light generated in each of the organic EL layers which is diffused into the region other than the light emission regions so that the portion of the light is transmitted through the separation wall portion and the sealing substrate to be viewable as an image on the sealing substrate.
