Document Type and Number:
WIPO Patent Application WO/2022/214904
Kind Code:
A1
Abstract:
The present invention provides a display device which has high display quality. This display device comprises a first pixel, a second pixel that is arranged adjacent to the first pixel, a first insulating layer, a second insulating layer that is arranged on the first insulating layer, and a third insulating layer that is arranged on the second insulating layer. The first pixel comprises a first pixel electrode, a first EL layer that is arranged on the first pixel electrode, and a common electrode that is arranged on the first EL layer. The second pixel comprises a second pixel electrode, a second EL layer that is arranged on the second pixel electrode, and the common electrode that is arranged on the second EL layer. The first insulating layer and the third insulating layer comprises an inorganic material; and the second insulating layer comprises an organic material. The second insulating layer overlaps with a lateral surface of the first EL layer and a lateral surface of the second EL layer, with the first insulating layer being interposed therebetween. The second insulating layer overlaps with the common electrode, with the third insulating layer being interposed therebetween. The third insulating layer is in contact with the first insulating layer in a region where the third insulating layer does not overlap with the second insulating layer.
