Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a manufacturing method thereof, and a display device. Background technique [0002] Liquid crystal display (LCD, Liquid Crystal Display) has the characteristics of small size, light weight, low power consumption, low radiation and low manufacturing cost, and has been widely used in various electronic devices, such as monitors, TVs, mobile phones, digital cameras, etc. digital electronics. Among them, TFT-LCD (Thin Film Transistor Liquid Crystal Display, Thin Film Transistor Liquid Crystal Display) is a main flat panel display device (FPD, Flat Panel Display). [0003] According to the direction of the electric field driving the liquid crystal, TFT-LCD is divided into vertical electric field type, horizontal electric field type and multi-dimensional electric field type. Among them, the vertical electric field type TFT-LCD needs to form pixel electrod...

Problems solved by technology

[0004] In the traditional HADS array substrate, the positions of the common electrode and the pixel electrode of the ADS array substrate are reversed. The process flow of the HADS array substrate is: forming gate electrode 2 and gate line → forming active layer 4 → forming source electrode 5 and drain electrode 6. Data line and pixel electrode 7 → form a common electrode, such as figure 1 and figure 2 As shown, the pixel electrode 7 and the drain electrode 6 are arranged on the same layer, and the pixel electrode 7 is directly overlapped on the drain electrode 6. However, since the thickness of the pixel electrode 7 is generally relatively thin, faults are likely to occur at the overlapping slope angle, resulting in The drain electrode 6 and the pixel electrode 7 are disconnected, so that the drain electrode 6 cannot provide data signals for the pixel electrode 7, thereby affecting the normal operation of the array substrate and reducing the product yield of the array substrate
