Abstract
A high-resolution display device is provided. A display device having both high display quality and high resolution is provided. The display device is provided with a structure that inhibits a reduction in contrast due to the light guided by a layer extending across light-emitting elements. A structure body that absorbs or reflects visible light is provided between adjacent light-emitting elements. This structure body absorbs or reflects the light emitted from a light-emitting element and traveling toward an adjacent pixel, whereby a reduction in contrast due to stray light is inhibited.
Claims9
A display device comprising:
- a first pixel electrode;
- a second pixel electrode;
- a first organic layer;
- a second organic layer;
- a common electrode;
- a resin layer;
- and
- an insulating layer,
- wherein the first organic layer is over the first pixel electrode,
- wherein the second organic layer is over the second pixel electrode,
- wherein the common electrode comprises:
- a portion overlapping with the first pixel electrode with the first organic layer therebetween;
- a portion overlapping with the second pixel electrode with the second organic layer therebetween;
- and
- a portion overlapping with the resin layer,
