Abstract
Provided is an organic EL device having high reliability, wherein decrease of the luminance due to the generation of a gas such as water vapor is suppressed. This organic EL device is provided with: an interlayer insulating film that is formed on a substrate; a lower electrode that is formed above the interlayer insulating film so as to correspond to a light emitting region; a light emitting layer that is formed on the lower electrode in the light emitting region; and an upper electrode that is formed on the light emitting layer. A gap is formed between the interlayer insulating film and the lower electrode.
Claims8
An organic electroluminescent device having a plurality of pixels each having a light-emitting region therein, comprising:
- a substrate;
- an insulating layer formed on the substrate;
- a plurality of lower electrodes formed over the insulating layer, respectively in the plurality of light-emitting regions;
- light-emitting layers formed respectively on the lower electrodes in the plurality of light-emitting regions;
- and
- an upper electrode formed on the light-emitting layers,
- wherein a void is formed between the insulating layer and the lower electrodes thereover, and
- wherein in plan view, an opening in the upper electrode is in a region between adjacent pixels, the opening being a through hole communicating with said void.
