Title:
LIGHT-EMITTING STRUCTURE, DISPLAY PANEL AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/215882
Kind Code:
A1
Abstract:
A light-emitting structure, a display panel and a display device. The light-emitting structure (100) comprises a first light-emitting element (110). The first light-emitting element (110) comprises a first light-emitting layer (111), a first electron transport layer (112) and a first cathode (113). The first cathode (113) is disposed contacting the first electron transport layer (112). The bottom of the conduction band of the first electron transport layer (112) is greater than the Fermi level of the first cathode (113). A difference between the bottom of the conduction band of the first electron transport layer (112) and the Fermi level of the first cathode (113) is in a range from 0.3 to 0.6 eV.
