Abstract

The invention provides a pixel electrode and a liquid crystal display panel. The pixel electrode comprises a frame (1), a plurality of mutually parallel and spaced first branch electrodes (21) and a plurality of mutually parallel and spaced second branch electrodes (22). The frame comprises a plurality of mutually connected frame electrodes, wherein the first branch electrodes (21) and the second branch electrodes (22) respectively form 45-degree included angles with the frame electrodes, the first branch electrodes (21) are mutually perpendicular to the second branch electrodes (22), one sub-pixel of the pixel electrode includes two regions, and keel-free or only-one-keel design is adopted, so that an effective display region is increased, and the penetration rate of the liquid crystal display panel is improved. One sub-pixel of the pixel electrode of the liquid crystal display panel includes two regions, and the keel-free or only-one-keel design is adopted, so that the penetration rate is higher, the backlight brightness demand is lower, and consumption of used power is lower.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a pixel electrode and a liquid crystal display panel. 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) type or super twisted nematic (Super Twisted Nematic, STN) type, plane switching ( In-Plane Switching (IPS) type, and vertical alignment (Vertical Alignment, VA) type. Compared with other types of liquid crystal displays, VA-type liquid crystal displays have extremely high contrast ratio, generally reaching 4000-8000, and are widely used in large-size displays, such as televisions. [0003] The reason why the VA-type liquid crystal display panel has a very high contrast is that in the dark state without ...
