Embodiment Construction

[0044] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0045] see Figure 5 to Figure 6 , the present invention firstly provides a pixel electrode, including a frame electrode 1, a trunk electrode 2 vertically connected to the middle of the frame electrode 1, several first branch electrodes 21 parallel to each other and spaced apart from each other, and several parallel electrodes 21 to each other. and the second branch electrodes 22 spaced apart from each other;

[0046] The main electrode 2 divides one side of the frame electrode 1 into a first region and a second region, and the plurality of first branch electrodes 21 are arranged on the second region at an angle of 135° with the frame electrode 1. In a region, and respectively connected to the frame electrode 1 or the main electrode 2, the pl...

Abstract

The invention provides a pixel electrode and a liquid crystal display panel. The pixel electrode comprises a frame electrode, a main electrode perpendicularly connected to the middle of the frame electrode, multiple first branch electrodes arranged in parallel and at intervals, and multiple second branch electrodes arranged in parallel and at intervals. The included angles between the first branch electrodes and the frame electrode and between the second electrodes and the frame electrode are 135 degrees and 45 degrees respectively, the first branch electrodes and the second branch electrodes are perpendicular, the pixel electrode comprises two regions in each sub-pixel, the design that only one keel is arranged is adopted, the effective display region is increased, and the penetration rate of the liquid crystal display panel is increased. According to the liquid crystal display panel, the pixel electrode comprises two regions in each sub-pixel, the design that only one keel is arranged is adopted, the penetration rate is high, the requirements for backlight brightness are low, and use power consumption is low.

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 ...
