Organic electro luminescent display device

摘要

An organic EL display device includes plural pixels that is arranged on a substrate in a matrix, a light shielding film that shields boundaries of the plurality of pixels, and a light emitting area in which an organic layer that is arranged between a lower electrode and an upper electrode, and formed of a plurality of layers including a light emitting layer that emits a light comes in contact with the lower electrode, in each of the plurality of pixels, in which the light shielding film has wide portions and narrow portions which are arranged along sides of the pixels, and different in width from each other.

主权项

1. An organic EL display device, comprising:
a plurality of pixels that is arranged on a substrate in a matrix; a light shielding film that shields boundaries of the plurality of pixels; and light emitting areas each of which is provided in each of the plurality of pixels and is an area where an organic layer makes contact with a lower electrode, the organic layer arranged between the lower electrode and an upper electrode, and formed of a plurality of layers including a light emitting layer, wherein each of the light emitting areas has a long side that extends along a side of a corresponding one of the plurality of pixels and a short side that extends along another side of the corresponding one of the plurality of pixels, the long side and the short side being different in length, wherein each of the light emitting areas is adjacent to another first one of the light emitting areas and another second one of the light emitting areas, wherein the short side of each of the light emitting areas lies next to the short side of the first one of the light emitting areas, wherein the long side of each of the light emitting areas lies next to the long side of the second one of the light emitting areas, wherein the light shielding film has a wide portion and a narrow portion which are different in width from each other, wherein the narrow portion is arranged along the short side so as to expose the short side, between each of the light emitting areas and the first one of the light emitting areas, and wherein the wide portion is arranged along the long side so as to cover the long side, between each of the light emitting areas and the second one of the light emitting areas.
