DISPLAY DEVICE, DISPLAY MODULE, ELECTRONIC DEVICE, AND METHOD FOR PRODUCING DISPLAY DEVICE

WIPO Patent Application WO/2023/073472

A1

The present invention provides a high-definition display device. This display device comprises a first light emitting device and a second light emitting device on an insulation surface. A first lateral insulating layer is in contact with the lateral surface of a first pixel electrode of the first light emitting device; and a second lateral insulating layer is in contact with the lateral surface of a second pixel electrode of the second light emitting device. The first light emitting device is superposed on a first colored layer, with a first color conversion layer being interposed therebetween. The first light emitting device and the second light emitting device share a common electrode. A first layer of the first light emitting device, a second layer of the second light emitting device, and a material layer that is positioned on the upper surface of an insulating layer between the first lateral insulating layer and the second lateral insulating layer have a same light emitting material, while being separated from each other.
