To further illustrate the technical means and effects of the present disclosure for achieving the intended purpose of disclosure, the following detailed description is given to the embodiments, structures, features and effects of the pixel electrode and the liquid crystal display panel according to the present disclosure with reference to the accompanying drawings and preferred embodiments.

As shown in fig. 1, a pixel electrode 10 provided in an embodiment of the present disclosure includes a frame electrode line 11, a plurality of main electrode lines 12, and a plurality of branch electrode lines 13.

The plurality of main electrode lines 12 include two main electrode lines 12 that intersect vertically, and the two main electrode lines 12 intersect vertically in the electrode area 100 to divide the electrode area 100 into four liquid crystal alignment regions. Namely, a first liquid crystal alignment region 101, a second liquid crystal alignment region 102, a third liquid crystal alignment region 103, and a fourth liquid crystal alignment region 104, which are adjacent in this order. Of course, the pixel electrode 10 may also include four main electrode lines 12 distributed in a cross shape, and the electrode area 100 is divided into four liquid crystal alignment regions. In each liquid crystal alignment region, a plurality of branch electrode lines 13 are distributed, and the plurality of branch electrode lines 13 are distributed at equal intervals and are parallel to each other. Each branch electrode line 13 forms an included angle with the frame electrode line 11 and the main electrode line 12.

Optionally, each branch electrode line 13 forms an included angle of 45 degrees with the main electrode line 12, that is, the branch electrode line 13 in the first liquid crystal alignment region 101 is perpendicular to the branch electrode line 13 in the second liquid crystal alignment region 102.

In each liquid crystal alignment region, at least three branch electrode lines 13 have different line widths. That is, the plurality of branch electrode lines 13 of each liquid crystal alignment region have at least three line widths. In each liquid crystal alignment area, the line width of the branch electrode line 13 with the longest line length is the largest, the line width of the branch electrode line 13 with the shortest line length is the smallest, the line width of the branch electrode line 13 with the middle line length is in the middle, and an equidifferent decreasing rule exists among the largest line width, the middle line width and the smallest line width. For example, in fig. 1, the branch electrode lines 13 in each liquid crystal alignment region have four line widths, where the maximum line width is L1, the minimum line width is L4, the line width of the branch electrode line 13 adjacent to L1 is L2, and the line width of the branch electrode line 13 adjacent to L4 is L3, so that there is a law that the differences among L1, L2, L3, and L4 decrease progressively.

Of course, it can be understood by those skilled in the art that, in addition to the structure shown in fig. 1, there may be three, five or more branch electrode lines 13 distributed in an equidifferent decreasing rule in each liquid crystal alignment region.

Namely, a first liquid crystal alignment region 301, a second liquid crystal alignment region 302, a third liquid crystal alignment region 303 and a fourth liquid crystal alignment region 304 which are adjacent in this order. In each liquid crystal alignment region, a plurality of branch electrode lines 33 are distributed evenly, and the plurality of branch electrode lines 33 are distributed at equal intervals and are parallel to each other. Each branch electrode line 33 forms an included angle with the frame electrode line 31 and the main electrode line 32.

The difference between the line width of the first connecting section 331 and the line width of the second connecting section 332 is 0.5 to 1 micrometer, the line width of the second connecting section 332 is 2 to 3 micrometers, and the line length of the first connecting section 331 and the line length of the second connecting section 332 are both 1 to 2 micrometers.

The pitch of the two adjacent branch electrode lines 33 may be between 2 micrometers and 4 micrometers.

As can be understood by those skilled in the art, in the present embodiment, the branch electrode lines 33 of the pixel electrode 30 are designed to have different line widths alternately distributed, so that the charge accumulation of the pixel electrode 30 is uniform and the electrode potential is uniform during the charging process, thereby improving the tilting speed and uniformity of the liquid crystal molecules under the applied voltage, i.e., improving the display effect.

As shown in fig. 4, a pixel electrode 40 provided in an embodiment of the present disclosure includes a frame electrode line 41, a plurality of main electrode lines 42, and a plurality of branch electrode lines 43.

Alternatively, the branch electrode lines 43 of two adjacent segment designs are respectively denoted by S1 and S2, and then the projection of the segment of S1 at S2 does not coincide with the segment of S2. That is, the branch electrode lines 43 of the adjacent two segment designs have different segment positions and have intervals, so that the electrodes have different charge accumulation paths due to the segments.

Of course, alternatively, the segment positions of the branch electrode lines 43 of the adjacent two segment designs may also be the same, i.e., the projection of the segment of S1 at S2 may also coincide with the segment of S2.

Alternatively, the main electrode line 42 is not connected to the frame electrode line 41. It can also be understood that both ends of the main electrode line 42 are also provided with a hollow design, so that both ends of the main electrode line 42 are connected with the branch electrode lines 43 with shorter line length, but are not connected with the frame electrode lines 41. Alternatively, the branch electrode lines 43 with longer line length in each liquid crystal alignment region are designed in a segmented manner, and the branch electrode lines 43 with shorter line length are continuous without segmentation.
