Document Type and Number:
WIPO Patent Application WO/2022/189883
Kind Code:
A1
Abstract:
Provided is a display apparatus exhibiting high definition or high resolution. This display apparatus has a first light emitting device, a second light emitting device, a first insulation layer, and a first layer. The first light emitting device has a first pixel electrode, a first light emitting layer on the first pixel electrode, and a common electrode on the first light emitting layer. The second light emitting device has a second pixel electrode, a second light emitting layer on the second pixel electrode, and a common electrode on the second light emitting layer. The first light emitting layer covers a side surface of the first pixel electrode. The second light emitting layer covers a side surface of the second pixel electrode. The first layer is located on the first light emitting layer. In a cross-sectional view, one end of the first layer is aligned or substantially aligned with an end of the first light emitting layer. Another end of the first layer is located on the first light emitting layer. The first insulation layer covers an upper surface of the first layer and a side surface of each of the first light emitting layer and the second light emitting layer. The common electrode is located on the first insulation layer.
