Problems solved by technology

[0005] image 3 Shown is the optical performance of the sub-pixel using the above-mentioned "m"-shaped pattern pixel electrode 70. Since the surrounding edges of the pixel electrode 70 are not neat, the direction of the corresponding fringe electric field is relatively disordered, and the orientation of the liquid crystal molecules located at the edge of the sub-pixel is also disordered. It is more messy, which affects the light transmittance, and dark lines will appear in the edge area of ​​​​the sub-pixels, resulting in a decrease in display quality

Embodiment Construction

[0041] 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.

[0042] see Figure 4 , the present invention firstly provides a pixel electrode, including: a trunk 11 , a plurality of pixel electrode branches 13 , a first closed frame 15 , and at least one second closed frame 17 .

[0043] The backbone 11 divides a sub-pixel into several domains. Usually, the backbone 11 is in the shape of a "ten", and the "ten"-shaped backbone 11 divides a sub-pixel into four domains; of course, the backbone 11 can also be in other shapes, and divides a sub-pixel into four domains. Greater number of domains.

[0044] The plurality of pixel electrode branches 13 extend from the trunk 11 in different directions in each domain, the plurality of pixel electrode branches 13 in one domain are parallel to each other and spaced...

Abstract

The invention provides a pixel electrode and a liquid crystal display panel. The pixel electrode is provided with a first closed frame (15) and at least one second closed frame (17), the first closed frame (15) is connected with the tail ends of all pixel electrode branches (13) and a trunk (11), and each second closed frame (17) sleeves the periphery of the first closed frame (15) and is connected with the trunk (11). The brim electric field of the pixel electrode is rectified through the first closed frame (15) and the second closed frames (17), so that orientations of liquid crystal molecules located at edges of subpixels are uniform, dark fringes at peripheral edges of the subpixels can be eliminated, and optical penetration rate of the liquid crystal display panel can be increased. Besides, a new domain is formed between the first closed frame (15) and the second closed frames (17), and the angle of view of the liquid crystal display panel on medium-low gray scale can be further improved.

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 panels (Thin Film Transistor-LCD, TFT-LCD) have been rapidly developed 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 -PlaneSwitching (IPS) type, and vertical alignment (Vertical Alignment, VA) type. Among them, the VA type liquid crystal display panel has a very high contrast ratio compared with other types of liquid crystal display panels, and is widely used in large-scale displays, such as liquid crystal televisions. [0003] like figure 1 As shown, a conventional VA liquid crystal display panel includes: an upper substrate 10, a lower substrate 20 ...
