Title:
ARRAY SUBSTRATE AND MANUFACTURING METHOD THEREFOR, DISPLAY PANEL AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/163940
Kind Code:
A1
Abstract:
An array substrate and a manufacturing method therefor, a display panel and a display device. The manufacturing method for an array substrate comprises: providing a base substrate (1); sequentially forming an electrode structure (2) on a first surface of the base substrate (1); forming a first protective structure (3) which covers the base substrate (1) on a side of the electrode structure (2) facing away from the base substrate (1); turning over the base substrate (1) so that the first protective structure (3) is attached to a bearing machine platform; forming a binding terminal (4) on a second surface of the base substrate (1), the second surface being arranged opposite the first surface; and turning over the base substrate (1) again, and patterning the first protective structure (3) to expose the electrode structure (2). The manufacturing method not only protects the electrode structure (2) on the first surface of the base substrate (1) to prevent the electrode structure (2) from being damaged, but also makes it unnecessary to tear off the first protective structure (3), thereby simplifying the manufacturing process and reducing the production cost.
