Abstract

The invention discloses an array substrate, a preparation method thereof, a display panel and a display device. At least two public electrode slots are formed. The problem that adjacent pixels are affected to cause color mixing is avoided, and meanwhile the liquid crystal efficiency is improved. The array substrate comprises a plurality of grid lines and a plurality of data lines which are crossed. A plurality of pixel areas are defined by the crossed grid lines and data lines. Each pixel area comprises a thin film transistor and further comprises a first insulation layer, a metal layer, a second insulation layer, a pixel electrode and a public electrode, wherein the first insulation layer is arranged above the thin film transistor and the corresponding data line, the metal layer is arranged above the first insulation layer, the second insulation layer is arranged above the metal layer, the pixel electrode and the public electrode are arranged above the second insulation layer, and a third insulation layer is arranged between the pixel electrode and the public electrode. The public electrode in each pixel area at least comprises two slots. The metal layers cover the data lines.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to an array substrate and a preparation method thereof, a display panel and a display device. Background technique [0002] With the development of liquid crystal display technology, flat panel displays have replaced CRT (Cathode Ray Tube, cathode ray tube) displays to become mainstream products in the display field. Currently, common flat panel displays include LCD (Liquid Crystal Display, liquid crystal display) and OLED (Organic Light-Emitting Diode, organic light-emitting diode) displays. During the imaging process, each liquid crystal pixel in the LCD display is integrated in a TFT (Thin Film Transistor, Thin Film Transistor) to drive, and cooperate with the peripheral driving circuit to realize image display. [0003] In the ADS (ADvanced Super Dimension Switch, advanced ultra-dimensional field switching technology) mode, two layers of transparent elect...
