Title:
DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/240718
Kind Code:
A1
Abstract:
A display panel (100) and a manufacturing method therefor, and a display device. The display panel comprises a substrate (10), an organic planarization layer (17), an anode (18), a light-emitting layer (20) and a cathode (21) which are sequentially arranged. The anode (18) comprises a hydrogen barrier layer (181), a reflective layer (182) and an electrode layer (183) which are sequentially arranged on the organic planarization layer (17). The reducibility of the metal in the reflective layer (182) is greater than the reducibility of hydrogen gas. The hydrogen barrier layer (181) is composed of a metallic or alloy material, and the reducibility of the metal in the hydrogen barrier layer (181) is less than the reducibility of hydrogen gas.
