Document Type and Number:
WIPO Patent Application WO/2021/114398
Kind Code:
A1
Abstract:
A manufacturing method for a display panel (100), and a display panel (100). The manufacturing method for a display panel (100) comprises: providing a substrate layer (10); depositing a transparent electrode layer (21) and a first metal layer (22) on the substrate layer (10), and etching the transparent electrode layer (21) and the first metal layer (22), so as to form a light blocking layer (20) and an anode (23); sequentially forming a buffer layer (30), an oxide layer (40), and an insulating layer (50) on the light blocking layer (20), the buffer layer (30) and the insulating layer (50) being formed by means of the same photomask; depositing a second metal layer (60) on the insulating layer (50), and etching the second metal layer (60), so as to form a source electrode (61), a gate electrode (62), and a drain electrode (63); and sequentially forming a pixel defining layer (70), a light-emitting layer (80), and a cathode layer (90) on the second metal layer (60).
