Document Type and Number:
WIPO Patent Application WO/2022/200914
Kind Code:
A1
Abstract:
Provided is a high-definition or high-resolution display device. The present invention includes a first light-emitting device, a second light-emitting device, a first insulating layer, a first coloring layer, and a second coloring layer. The first light-emitting device includes a first pixel electrode, a first light-emitting layer over the first pixel electrode, and a common electrode over the first light-emitting layer. The second light-emitting device includes a second pixel electrode, a second light-emitting layer over the second pixel electrode, and a common electrode over the second light-emitting layer. The first insulating layer covers the individual side faces of the first pixel electrode, the second pixel electrode, the first light-emitting layer, and the second light-emitting layer. The first coloring layer is disposed in a manner superimposed over the first light-emitting device. The second coloring layer is disposed in a manner superimposed over the second light-emitting device. The first light-emitting device and the second light-emitting device each have a function for emitting white light. The first coloring layer has a function for transmitting visible light having a color different from that of visible light transmitted by the second coloring layer.
