Abstract

A liquid crystal display panel includes a first substrate, a second substrate opposite to the first substrate, a plurality of scan lines, a plurality of data lines intersecting with the scan lines, a plurality of pixel areas defined by the scan lines and the data lines, and a plurality of electrodes. Each electrode is positioned in a corresponding pixel area. Each pixel area has an inner surface. The electrode includes a branch portion, a frame connected to the branch portion, and a plurality of first slits defined by the frame and the branch portion, away from the inner surface of the pixel area.

Claims (32)

1. A liquid crystal display panel, comprising:

a first substrate;

a second substrate opposite to the first substrate;

a plurality of scan lines;

a plurality of data lines intersecting with the scan lines;

a plurality of pixel areas each having a boundary defined by two adjacent ones of the scan lines and two adjacent ones of the data lines, ; and

a plurality of electrodes, wherein each electrode is positioned in a corresponding pixel area and comprises:

a branch portion;

a frame connected to the branch portion;

a plurality of first slits defined by the frame and the branch portion, wherein each of the first slits has a closed end adjacent to the boundary, the frame being disposed between the boundary and the closed ends of the first slits; and

a plurality of second slits defined by the frame and the branch portion and each extending through the frame to the boundary, at least one of the second slits being disposed between two adjacent ones of the first slits that extend substantially parallel to each other.

2. The liquid crystal display panel of claim 1 , wherein the branch portion comprises a central segment extending along a first axis and an extending segment symmetrically extending from the central segment toward the outside and connecting to the frame.

3. The liquid crystal display panel of claim 2 , wherein the branch portion is substantially fishbone-shaped.

4. The liquid crystal display panel of claim 2 , wherein the frame is substantially rectangular.

5. The liquid crystal display panel of claim 2 , wherein each first slit is substantially polygonal.

6. The liquid crystal display panel of claim 1 , wherein the second slits are symmetrically defined on both sides of the branch portion.

7. The liquid crystal display panel of claim 1 , wherein each of the second slits has an opening in proximity to the boundary, and a length of projection of the opening of each of the second slits on the pixel area equals or is less than 40% of that of the boundary of the pixel area.

8. A liquid crystal display panel comprising:

a first substrate;

a second substrate opposite to the first substrate;

a plurality of scan lines;

a plurality of data lines intersecting with the scan lines;

a plurality of pixel areas each having a boundary defined by two adjacent ones of the scan lines and two adjacent ones of the data lines; and

a plurality of electrodes, wherein each electrode is positioned in a corresponding pixel area and comprises:

a branch portion;

a frame connected to the branch portion;

a plurality of first slits defined by the frame and the branch portion, wherein each of the first slits has a closed end adjacent to the boundary, the frame being disposed between the boundary and the closed ends of the first slits; and

a plurality of second slits defined by the frame and the branch portion, wherein the second slits extend through an cdgc of the frame to the boundary, and only one of the second slits is disposed between at least an adjacent pair of the first slits.

9. The liquid crystal display panel of claim 8 , wherein the branch portion comprises a central segment extending along a first axis and an extending segment symmetrically extending from the central segment toward the outside and connecting to the frame.

10. The liquid crystal display panel of claim 8 , wherein the second slits are symmetrically disposed at both sides of the branch portion.

11. The liquid crystal display panel of claim 8 , wherein the frame is substantially rectangular.

12. The liquid crystal display panel of claim 8 , wherein each first slit is substantially polygonal.
