Title:
TFT ARRAY SUBSTRATE AND DISPLAY PANEL COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2021/027053
Kind Code:
A1
Abstract:
A TFT array substrate, comprising a substrate layer (10) and a metal layer (11, 12) provided on the substrate layer (10). The metal layer (11, 12) comprises a first metal layer (110, 120) and a second metal layer (112, 122) provided on the first metal layer (110, 120); the first metal layer (110, 120) comprises a main body portion (111, 121) and tail portions (113, 123); the main body portion (111, 121) of the first metal layer (110, 120) upwardly corresponds to the second metal layer (112, 122), and the tail portions (113, 123) of the first metal layer (110, 120) are the portions of the first metal layer (110, 120) extending from the side end portions of the main body portion (111, 121) to the outside of the second metal layer (112, 122). The TFT array substrate uses the topographical features of a novel metal layer (11, 12), thereby effectively improving the light leakage situation of the array substrate where the metal layer is located in a dark state, and further improving the contrast of a product.
