Title:
DISPLAY DEVICE, DISPLAY MODULE, AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/126749
Kind Code:
A1
Abstract:
The present invention provides a high-definition display device. This display device has a first light emitting device, a second light emitting device, a first insulating layer, a second insulating layer, a first colored layer, and a second colored layer. The first light emitting device has a first pixel electrode, a first layer, and a common electrode in this order on a first insulating layer. The second light emitting device has a second pixel electrode, a second layer, and the common electrode in this order on the first insulating layer. The first insulating layer has a groove having a region overlapping the first pixel electrode and a region overlapping the second pixel electrode, and the second insulating layer overlaps a side surface of the first layer, a side surface of the second layer, and the groove. The common electrode has a section positioned on the second insulating layer. The first colored layer overlaps with the first light emitting device. The second colored layer overlaps with the second light emitting device and transmits light of a different color than the first colored layer. The first layer and the second layer have mutually the same light emitting material and are separated from each other.
