  • Array substrate and manufacturing method thereof, display device
    Patent number: 10629633
    Abstract: A manufacturing method of an array substrate is disclosed. The manufacturing method includes a step of forming a pattern including a pixel electrode; and the manufacturing method further includes a step of forming a pattern including an active layer after the step of forming the pattern including the pixel electrode. Accordingly, an array substrate and a display device are also disclosed. In the manufacturing process of the array substrate, conductive material remained on the active layer is less, thereby producing less leak current, which in turn improves quality of the array substrate and display performance of the display device.
    Type: Grant
    Filed: June 28, 2019
    Date of Patent: April 21, 2020
    Assignees: BOE TECHNOLOGY GROUP CO., LTD., BEIJING BOE OPTOELECTRONICS TECHNOLOGY CO., LTD.
