Problems solved by technology

[0004] In the manufacturing process of the HVA display, the alignment film on the TFT substrate and the CF substrate is generally exposed and aligned through a specific mask. Repeated exposure, the area of ​​repeated exposure forms dark lines due to the polarization angle of the upper and lower alignment films, such as figure 1 As shown, the dark lines 100 are generally in the shape of a "cross" and are located in the center of each sub-pixel 200, thereby affecting the transmittance and display effect of the liquid crystal display panel.

Abstract

The invention provides a pixel electrode structure which adopts the structure that several sub-electrodes in the cross area among a first electrode, a second electrode, a third electrode and a fourth electrode are distributed at intervals and V-shaped, so that slots are formed among the sub-electrodes to adjust the guiding direction of liquid crystal molecules in the cross area, and ensure that the guiding direction of liquid crystal molecules in the cross area is in accordance with that of the liquid crystal molecules in the areas of the first electrode, the second electrode, the third electrode and the fourth electrode. Therefore, the cross dark lines in each sub-pixel of an LCD panel are reduced, the light-transmitting area is enlarged, and the permeability and the display quality of a product are improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel electrode structure. Background technique [0002] Active thin film transistor liquid crystal display (Thin Film Transistor-LCD, TFT-LCD) has been developed rapidly and widely used in recent years. As far as TFT-LCD display panels currently on the mainstream market are concerned, they can be divided into three types, namely Twisted Nematic (TN) or Super Twisted Nematic (STN) type, in-plane switching (In -Plane Switching (IPS) type, Vertical Alignment (VA) type, and High Vertical Alignment (HVA) type. [0003] Generally, a liquid crystal display device includes a housing, a liquid crystal panel disposed in the housing, and a backlight module disposed in the housing. Among them, the structure of the liquid crystal panel is mainly composed of a thin film transistor array substrate (Thin FilmTransistor Array Substrate, TFT Array Substrate), a color filter substrate...
