PIXEL UNIT, DISPLAY PANEL, DISPLAY DEVICE, AND METHOD FOR MANUFACTURING PIXEL UNIT

WIPO Patent Application WO/2019/201104

A1

Provided are a pixel unit, a display panel, a display device, and a method for manufacturing a pixel unit. The pixel unit comprises a first sub-pixel unit and a second sub-pixel unit, each comprising a first electrode (002), a light-emitting layer (003) and a second electrode (004) stacked on a substrate (001) in a direction away from the substrate (001). The light emission lifetime of the light-emitting layer (003) of the first sub-pixel unit is less than the light emission lifetime of the light-emitting layer (003) of the second sub-pixel unit. The area of the orthographic projection of the light-emitting layer (003) of the first sub-pixel unit on the substrate (001) is equal to the area of the orthographic projection of the light-emitting layer (003) of the second sub-pixel unit on the substrate (001). The area of the orthographic projection of the first electrode (002) of the first sub-pixel unit on the substrate (001) is greater than the area of the orthographic projection of the first electrode (002) of the second sub-pixel unit on the substrate (001).
