Problems solved by technology

Furthermore, the voltage signal transmitted through the data line is likely to burst out from the distance between the two branch electrodes to generate an electric field, which makes the direction of the liquid crystal molecules fall out of order.
In this way, the pixels originally scheduled to display low grayscale values ​​may have light leakage and affect the display quality

[0058] Please refer to Figure 4 , which shows a top view of part of the liquid crystal panel according to the third embodiment of the present invention. Compared with the first embodiment, the configuration of the pixel electrode 350 is slightly different. The main body 151 is located in the pixel area Ap, and the first branch electrode 1531 extends from the main body 151 in the pixel area Ap. However, the second branch electrode 3532 in this embodiment extends outward from the main body 151 and crosses over the scanning line 140s. Other similar structures will not be described repeatedly.

[0059] In this way, the liquid crystal panel of this embodiment can achieve the effect similar to the liquid crystal panel of the first embodiment, so that the liquid crystal molecules above the scan line 140s are not easily affected by the electric field to cause light leakage, so as to improve the display quality. In addition, the transmittance of the pixels can still be maintained. ...

Abstract

The invention relates to a liquid crystal panel which comprises a first substrate, a second substrate, a liquid crystal layer, a plurality of data wires, a plurality of scanning wires and a plurality of pixel electrodes, wherein the liquid crystal layer is positioned between the first substrate and the second substrate; two adjacent data wires and two adjacent scanning wires are staggered to form a pixel region; each pixel electrode comprises a main body positioned in the pixel region, a plurality of first branch electrodes and a plurality of second branch electrodes; the first branch electrodes extend from each main body towards the pixel region; the second branch electrodes outwards extend from each main body and across the upper sides of the data wires; first distances are reserved between the two adjacent first branch electrodes; second distances are reserved between the two adjacent second branch electrodes; and each second distance is smaller than each first distance.

Description

technical field [0001] The present invention relates to a liquid crystal panel, and in particular to a liquid crystal panel with a pixel electrode having a branch structure. Background technique [0002] In a liquid crystal panel, two adjacent data lines and two adjacent scan lines are interlaced to form a pixel area. In the conventional arrangement of pixel electrodes, the pixel electrodes are only arranged in the pixel area without overlapping with the data lines, so as to avoid the generation of parasitic capacitance between the pixel electrodes made of metal materials and the data lines made of metal materials. However, this configuration often leads to a reduction in the aperture ratio of the pixels. In addition, in order to avoid alignment errors when the pixel electrodes are disposed in the pixel area, the size of the pixel electrodes is usually reduced, so that the aperture ratio is further reduced. [0003] With the development and research of various materials, f...
