Abstract

The invention provides an array substrate and a manufacturing method therefor and a display apparatus. Each of a switching thin film transistor and a driving thin film transistor in the array substrate comprises an active layer, a planarization gate insulating layer and a gate separately; the active layers are both arranged on a substrate; the thickness of the active layer of the switching thin film transistor is greater than that of the active layer of the driving thin film transistor; the switching thin film transistor and the driving thin film transistor share the planarization gate insulating layer, and are arranged on the active layers and the exposed substrate; and the gate of the switching thin film transistor and the gate of the driving thin film transistor are arranged on the planarization gate insulating layer. The process is simple and the manufacturing efficiency of the array substrate can be improved.

Description

technical field [0001] The present invention belongs to the field of display technology, and in particular, relates to an array substrate, a manufacturing method thereof, and a display device. Background technique [0002] The flat panel display device has many advantages such as thin body, power saving, and no radiation, so it has been widely used. Flat panel display devices mainly include Liquid Crystal Display (LCD for short) and Organic Light Emitting Diode (OLED for short) displays. OLED has the following excellent characteristics: ① self-illumination, no backlight required; ② high contrast; ③ thin thickness; ④ wide viewing angle; ⑤ fast response; ⑥ can be used for flexible panels; The manufacturing process is simple, so it is regarded as a new application technology for the next generation of flat panel displays. [0003] Organic light emitting diode displays can be divided into passive matrix organic light emitting diode displays (Passive Matrix Organic Light Emitti...
