Title:
DISPLAY PANEL AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/077801
Kind Code:
A1
Abstract:
Disclosed are a display panel and a display device. The display panel comprises a blue light-emitting device. The blue light-emitting device comprises a first electrode, an electron blocking layer, a light-emitting layer, and a second electrode that are stacked; wherein the hole mobility of the electron blocking layer is not greater than 5*10 -4cm 2/VS, so that the electrons and holes in the light-emitting layer tend to balance, and the luminous efficiency of the blue light-emitting device under low brightness is improved. The stability of the luminous efficiency of the blue light-emitting device under different light-emitting brightness is improved, thereby improving the color shift that occurs when light-emitting devices of different colors are mixed to form a corresponding color at a low brightness.
