Title:
ARRAY SUBSTRATE AND MANUFACTURING METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/024256
Kind Code:
A1
Abstract:
The present invention relates to the technical field of display, and provides an array substrate and a manufacturing method therefor, and a display device. The array substrate comprises a substrate, and a plurality of subpixels arranged on the substrate in an array mode and a thin film transistor driving each subpixel; the array substrate comprises a pixel electrode; and a channel region of the thin film transistor comprises a metal oxide semiconductor layer, the pixel electrode is a metal oxide conductive layer formed by conductorizing a metal oxide semiconductor, and the channel region of the thin film transistor is formed after being patterned using the same metal oxide semiconductor layer as the pixel electrode. In the embodiments of the present invention, on the basis of a same metal oxide semiconductor layer, a channel region of a semiconductor and a conductive pixel electrode can be formed by only one patterning, thereby reducing the patterning process of a mask, simplifying process steps, and reducing process complexity.
