Array substrate, manufacturing method thereof, and display device

Abstract

The invention discloses an array substrate, a manufacturing method thereof, and a display device. The array substrate comprises a substrate body, a thin film transistor, a first public electrode, a pixel electrode and a second public electrode which are formed above the substrate body. The pixel electrode is located between the first public electrode and the second public electrode. The pixel electrode is electrically connected with the drain of the thin film transistor. The pixel electrode are insulated with the first public electrode and the second public electrode. The potential of the first public electrode is equal to the potential of the second public electrode. Due to the fact that a first capacitor is formed between the first public electrode and the pixel electrode, a second capacitor is formed between the second public electrode and the pixel electrode, and the first capacitor and the second capacitor are parallelly connected, the capacity of a storage capacitor in a pixel unit is equal to the capacity sum of the first capacitor and the second capacitor, and the capacity of the storage capacitor in the pixel unit is increased effectively.

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] Thin Film Transistor Liquid Crystal Display (TFT-LCD for short) has the characteristics of small size, low power consumption, and no radiation, and occupies a dominant position in the current flat panel display market. [0003] Fringe Field Switching (FFS for short) generates a fringe electric field through the electrodes between pixels in the same plane, so that the aligned liquid crystal molecules between the electrodes and directly above the electrodes can be rotated in the direction parallel to the plane of the substrate. While improving the viewing angle, the light transmission efficiency of the liquid crystal layer is improved. [0004] In the display device of FFS type, an array substrate is included, and the array substrate includes: a pixel electrode and a co...

AI Technical Summary

Problems solved by technology

[0006] The present invention provides an array substrate, a manufacturing method thereof, and a display device, which are used to solve the problem that the areas of the pixel electrodes and the common electrodes are both reduced in the prior art, which leads to the reduction of the storage capacitance in the pixel unit, which in turn causes the pixel to be damaged during the display stage. The voltage on the electrode is unstable, and the technical problem that the pixel unit cannot emit light normally
