MANUFACTURING METHOD FOR ARRAY SUBSTRATE, ARRAY SUBSTRATE AND DISPLAY DEVICE

摘要

A manufacturing method for an array substrate, an array substrate and a display device. The method comprises: forming a gate line (11), a gate electrode (1) and a gate insulating layer (2) which covers the gate line and the gate electrode on a first surface of a substrate body (9); forming a semiconductor thin film (32) on the gate insulating layer (2); patterning the semicondumctor thin film (32) by taking the gate electrode (1) and the gate line (11) as masks, so as to form a source semiconductor layer located inside a region where the gate line and the gate electrode are located; and manufacturing a target semiconductor layer (13) using the source semiconductor layer. The present invention can avoid dislocation of an active layer, thus avoiding the problem of non-uniform brightness of a display caused by the dislocation of the active layer.
