Multi-domain vertical alignment liquid crystal display panel and thin film transistor array thereof

Abstract

Disclosed a re a multiple area vertical arrangement liquid crystal display panel and the thin film transistor array of the same. The thin film transistor array comprises base board and scanning wiring installed on the base board, data wiring, thin film transistors and pixel electrodes, wherein the scanning wiring and the data wiring separate plural pixel areas on the base board; and the pixel electrodes and the thin film transistors are all installed in the pixel areas. The pixel electrodes have multiple main slits and flank slits, and the flank slits are connected on the side of the main slits, and each main slit has at least one snaking top which is on the edge of its adjacent pixel electrode for changing the electricity field direction of the pixel electrode edge, and making the inclining directions of all liquid crystal molecules uniform.

Description

technical field [0001] The present invention relates to a display panel, and in particular to a multi-domain vertical alignment (MVA) liquid crystal display panel and a thin film transistor array thereof. Background technique [0002] The rapid progress of the multimedia society is mostly due to the rapid progress of semiconductor components or display devices. As far as displays are concerned, thin film transistor liquid crystal displays (Thin Film Transistor Liquid Crystal Display, TFT-LCD) with superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation have gradually become the mainstream of the market. [0003] At present, the performance requirements of the market for liquid crystal displays are towards high contrast ratio (High ContrastRatio), no grayscale inversion (No Gray Scale Inversion), small color shift (Little Color Shift), high brightness (High Luminance), and high color richness , high colo...

Problems solved by technology

Please refer to figure 2 According to the principle of boundary effect in electromagnetism, the direction of the electric field at the edge of the pixel electrode 103 is opposite to the direction of the electric field at other parts of the pixel electrode 103 (here it can be assumed that a dummy alignment protrusion 114 is arranged on the edge of the pixel electrode 103, such as figure 2 As shown), the tilting direction of the liquid crystal molecules 105 located at the edge of the pixel electrode 103 is inconsistent, and then black lines (disclination) are generated in the area 116, so that the light transmittance of the multi-area vertically aligned liquid crystal display panel 100 is reduced, and the response time is increased.
