TFT (Thin Film Transistor) array substrate and liquid crystal display panel

Abstract

The invention discloses a TFT (Thin Film Transistor) array substrate. The TFT array substrate comprises a pixel array which is formed on the TFT array substrate; every pixel is provided with a pixel electrode layer and a public electrode layer; every pixel electrode layer is provided with a pixel electrode; every public electrode layer is provided with a first public electrode and a second public electrode, wherein every second public electrode is connected with the corresponding first public electrode; every first public electrode is located in a pixel area; every second public electrode is located between the two corresponding adjacent pixels; the projection of every second public electrode on the corresponding pixel electrode layer and the two adjacent pixel electrodes are partially overlapped; every pixel comprises a data line which is located in the pixel area; the projection of every data line on the corresponding public electrode layer and the corresponding second public electrode are not overlapped. According to the TFT array substrate and a liquid crystal display panel, every second public electrode is arranged between the two corresponding adjacent pixel electrodes so as to ensure that liquid crystal molecules within the electric field line control range of every second public electrode do not deflect freely and accordingly the light leakage is avoided.

Description

technical field [0001] The invention relates to a TFT array substrate and a liquid crystal display panel comprising the TFT array substrate. Background technique [0002] In recent years, flat-panel displays have been favored by people, and the requirements for display quality have been continuously improved. The aperture ratio of liquid crystal displays is one of the important factors affecting the display quality of display devices. A lower aperture ratio not only affects the quality of the screen, but also affects the display quality. power consumption of the device. There are many factors affecting the aperture ratio of a liquid crystal display device, one of which is Beating Mura (squeeze chromatic aberration). When the panel is squeezed, the relative displacement between the color filter substrate (CF) and the TFT substrate will occur, and light leakage will occur at the position that cannot be blocked by the black matrix (BM) of the color filter substrate after dislo...

Problems solved by technology

However, the extension of the black matrix will lead to an increase in the overlapping portion of the pixel unit between the BM and the TFT substrate, thereby greatly reducing the pixel aperture ratio, thereby affecting the quality of the display screen
