THIN FILM TRANSISTOR ARRAY SUBSTRATE

摘要

A thin film transistor array substrate, including a plurality of scanning lines (120), data lines (140) and common electrode lines (160) formed on a substrate (100). The plurality of scanning lines (120) and data lines (140) mutually define a plurality of pixel areas (200), a thin film transistor (150) is formed at the interleaved portion thereof, and a plurality of pixel electrodes (220) are formed inside the plurality of pixel areas (200). The thin film transistor array substrate further includes a patterned shield layer (180), wherein the patterned shield layer (108) is disposed under the plurality of data lines (140) in an insulated manner. The patterned shield layer (180) in the present invention can directly shield the backlight (10) and can reduce the area of the black matrix (350) on the CF substrate (300) and improve the aperture ratio.
