Document Type and Number:
WIPO Patent Application WO/2023/084355
Kind Code:
A1
Abstract:
Provided is a high-definition display device. The display device has a first light emission device, a second light emission device, a first sidewall insulation layer, a second sidewall insulation layer, an insulation layer, a first coloration layer, and a second coloration layer. The first light emission device has a first pixel electrode, a first EL layer, and a common electrode. The second light emission device has a second pixel electrode, a second EL layer, and a common electrode. The first EL layer and the second EL layer display white light. The first sidewall insulation layer contacts a side surface of the first pixel electrode, and the second sidewall insulation layer contacts a side surface of the second pixel electrode. The insulation layer covers a side surface and a part of the upper surface of the first EL layer, and a side surface and a part of the upper surface of the second EL layer. The first coloration layer overlaps with the first light emission device, and the second coloration layer overlaps with the second light emission device. The first coloration layer and the second coloration layer each have a function of transmitting light of a different color.
