Document Type and Number:
WIPO Patent Application WO/2018/223642
Kind Code:
A1
Abstract:
An array substrate and a manufacturing method thereof, a display panel, and a display device. The array substrate comprises: an active layer (11) provided on a substrate (10), the active layer (11) comprising a channel region (11C), a source/drain region (11SD) provided on two sides of the channel region (11C), and a lightly-doped drain region (11L) provided between the channel region (11C) and the source/drain region (11SD); a gate electrode (121) and a first electrode (122) provided on the active layer (11); a first insulation layer (13) provided on the gate electrode (121) and the first electrode (122); and a blocking portion (141) and a second electrode (142) provided on the first insulation layer (13). A projection of the second electrode (142) on the substrate (10) at least partially overlaps a projection of the first electrode (122) on the substrate (10). A projection of the blocking portion (141) on the substrate (10) covers a projection of the lightly-doped drain region (11L) on the substrate (10), and does not overlap a projection of the source/drain region (11SD) on the substrate (10). The blocking portion (141) and the second electrode (142) are provided on the same layer.
