Problems solved by technology

However, when the data lines DL with opposite polarities on both sides send signals at the same time, one side will be subject to strong capacitive coupling (coupling), so the parasitic capacitance of the pixel is less likely to be balanced when it is affected by the data lines on both sides.
Another way of division is the design that the dark area A2 surrounds the bright area A1, such as Figure 1C As shown in the schematic diagram of , although this design has a good balance effect on the influence of the data line, the efficiency of the liquid crystal is deteriorated and the transmittance is reduced due to the excessively long junction of the dark area A2 and the bright area A1.

Abstract

The invention discloses a thin film transistor substrate, which comprises a substrate, a plurality of data lines, a plurality of scanning lines and a plurality of pixel electrodes. The data lines and the scanning lines are crossed to be arranged on the substrate. A plurality of pixel regions can be defined by the data lines and the scanning lines. The pixel electrodes are correspondingly arranged in the pixel regions. At least two slits are formed in each pixel electrode. The slits divide the corresponding pixel electrodes into at least two first regions and at least two second regions respectively. The first regions are electrically insulated from the second regions. The first regions are arranged diagonally. The second regions are arranged diagonally.

Description

technical field [0001] The invention relates to a liquid crystal display panel, in particular to a liquid crystal display panel and a thin film transistor substrate thereof. Background technique [0002] Liquid Crystal Display (LCD) devices have been used in various electronic products due to their advantages of low power consumption, low heat generation, light weight, and non-radiation, and are gradually replacing traditional Cathode Ray Tube (CRT) display device. [0003] Generally speaking, a liquid crystal display device mainly includes a liquid crystal display panel (LCD Panel) and a backlight module (Backlight Module). Wherein, the liquid crystal display panel mainly includes a thin film transistor substrate, a color filter substrate and a liquid crystal layer, and a plurality of pixels arranged in an array are arranged on the two substrates. The backlight module can evenly distribute light from the light source to the liquid crystal display panel, and display colors...
