WIPO Patent Application WO/2023/057855
Kind Code:
A1
Abstract:
The present invention provides a high-definition display device. This display device comprises first to third light-emitting devices, first and second colored layers, and first and second insulating layers, the first light-emitting device having a first pixel electrode, a first light-emitting layer, and a common electrode, the second light-emitting device having a second pixel electrode, a second light-emitting layer, and the common electrode, the third light-emitting device having a third pixel electrode, a third light-emitting layer, and the common electrode, the first light-emitting layer and the second light-emitting layer having the same light-emitting material, the third light-emitting device emitting light having a wavelength shorter than that of the light emitted by the first and second light-emitting devices, the first colored layer overlapping the first light-emitting device, the second colored layer overlapping the second light-emitting device and transmitting light of a different color than the first colored layer, the first insulating layer and the second insulating layer overlapping a portion of the upper surface and side surfaces of the first light-emitting layer and a portion of the upper surface and side surfaces of the second light-emitting layer, and the common electrode covering the upper surface of the second insulating layer.
