Patent ID: 8854584

Claim:
A pixel electrode of a liquid crystal display (LCD) panel, the LCD panel comprising a substrate, a plurality of scan lines and a plurality of data lines formed on the substrate, and a plurality of switch units; the scan lines being parallel with each other, the data lines being parallel with each other and perpendicular to the scan lines, the switch units being electrically connected to the scan lines and the data lines respectively, every two adjacent ones of the scan lines intersecting with two adjacent ones of the data lines to form a pixel region on the substrate, and the pixel electrode being disposed in the pixel region and being located on the substrate, wherein the pixel electrode comprises: a peripheral portion in a rectangular frame form, being formed on the substrate and electrically connected to the switch units; branch portions located on the substrate and inside the rectangular frame of the peripheral portion, being electrically connected to the peripheral portion, wherein the branch portions include a first branch portion and a second branch portion, the first branch portion and the second branch portion are located in different regions inside the rectangular frame of the peripheral portion, the first branch portion comprises a plurality of first branches parallel with each other, and the second branch portion comprises a plurality of second branches parallel with each other; and an opening portion located on the substrate and inside the rectangular frame of the peripheral portion, wherein the opening portion comprises a first opening and a second opening, the first opening is perpendicularly connected with the first branches and is located on a midperpendicular of the first branches, the second opening is perpendicularly connected with the second branches and is located on a midperpendicular of the second branches, an extension line of the first opening intersects with one of the scan lines and one of the data lines to form a right triangle, and an extension line of the second opening intersects with one of the scan lines and one of the data lines to form a right triangle; the branch portions further include a third branch portion and a fourth branch portion formed on the substrate, the third branch portion is integral with the first branch portion, and the fourth branch portion is integral with the second branch portion; the third branch portion comprises a plurality of third branches parallel with each other and corresponding to the first branches in one-to-one correspondence, the fourth branch portion comprises a plurality of fourth branches parallel with each other and corresponding to the second branches in one-to-one correspondence, the first branches connect with the first opening via the third branches, and the third branches are arranged obliquely with respect to the first opening; and the second branches connect with the second opening via the fourth branches, and the fourth branches are arranged obliquely with respect to the second opening.
