DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/263969
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 positioned next to the first light emission device, a third light emission device positioned next to the second light emission device, a first insulating layer, and a second insulating layer. The first insulating layer has a first region between the first light emission device and the second light emission device, and a second region between the second light emission device and the third light emission device. The second insulating layer has a region positioned on a lower electrode of the third light emission device. The thickness of a third organic compound layer of the third light emission device is different from the thickness of a first organic compound layer of the first light emission device. The thickness of the third organic compound layer of the third light emission device is different from the thickness of a second organic compound layer of the second light emission device. In a cross-sectional view, the first insulating layer is provided so that the height from the lower surface of the lower electrode of the third light emission device is aligned with the height from the lower surface of a lower electrode of the second light emission device.
