Title: ARRAY SUBSTRATE AND MANUFACTURING METHOD THEREFOR, AND DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR
Abstract:
Disclosed are an array substrate and a manufacturing method therefor, and a display panel and a manufacturing method therefor, which relate to the technical field of display. The manufacturing method for an array substrate comprises: forming a gate metal layer (10) on a substrate (01) by means of one patterning process, and forming a gate insulation layer (11) on the gate metal layer (10); forming, by means of one patterning process, a semiconductor layer (12) and a source-drain metal layer (13) on the substrate (01) where the gate metal layer (10) and the gate insulation layer (11) are formed, wherein the source-drain metal layer (13) comprises a data line (131) and a metal electrode (132) connected to the data line (131); forming, by means of one patterning process, a first electrode (141) on the substrate (01) where the semiconductor layer (12) and the source-drain metal layer (13) are formed, and forming a channel region, wherein the channel region enables the metal electrode (132) to form a source electrode (1321) and a drain electrode (1322); forming, by means of one patterning process, a passivation layer (161) and an organic insulation layer (171) on the substrate (01) where the first electrode (141) is formed, wherein the organic insulation layer (171) at least corresponds to the data line (131); and forming, by means of one patterning process, a second electrode (18) on the substrate (01) where the organic insulation layer (171) is formed.
