DISPLAY DEVICE, FABRICATION METHOD FOR DISPLAY DEVICE, DISPLAY MODULE, AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/200916
Kind Code:
A1
Abstract:
The present invention provides a display device having high display quality and reliability. This display device comprises: a first light-emitting element; a second light-emitting element disposed so as to be adjacent to the first light-emitting element; a first protective layer; a second protective layer; and an insulating layer. The first light-emitting element has a first pixel electrode, a first EL layer, a light-emitting layer, and a common electrode. The second light-receiving element has a second pixel electrode, a second EL layer, and the common electrode. The first EL layer is provided on the first pixel electrode, and the second EL layer is provided on the second pixel electrode. The first protective layer has a region that contacts a side surface of the first EL layer, and the second protective layer has a region that contacts a side surface of the second EL layer. The insulating layer is provided between the first protective layer and the second protective layer. The common electrode is provided on the first EL layer, on the second EL layer, on the first protective layer, on the second protective layer, and on the insulating layer.
