Abstract

The disclosure provides a display apparatus having a pixel unit. The pixel unit include a first sub-pixel electrode and a second sub-pixel electrode. The first sub-pixel electrode includes a first main segment extending along a first direction, a first sub-segment extending along a second direction, and a third sub-segment extending along a third direction. The first sub-segment and the second sub-segment are respectively connected with the first main segment and located at two opposite ends of the first main segment. The second sub-pixel electrode is disposed adjacent to the first sub-pixel electrode and includes a second main segment extending along a fourth direction. The first direction is different from the fourth direction, the second direction is different from the first direction, and the third direction is different from the first direction.

First claim

What is claimed is:

1 . A display apparatus, having a pixel unit, wherein the pixel unit comprises:
a first sub-pixel electrode, comprising:
a first main segment, extending along a first direction;
a first sub-segment, extending along a second direction; and
a second sub-segment, extending along a third direction,
wherein the first sub-segment and the second sub-segment are respectively connected with the first main segment and are located at two opposite ends of the first main segment; and a second sub-pixel electrode, disposed adjacent to the first sub-pixel electrode and comprising:
a second main segment, extending along a fourth direction,
wherein the first direction is different from the fourth direction, the second direction is different from the first direction, and the third direction is different from the first direction.

2 . The display apparatus as claimed in claim 1 , wherein the first sub-pixel electrode further comprises:
a connection segment, connected with the first sub-segment, wherein an extending direction of the connection segment is different from the first direction, the second direction, the third direction, or the fourth direction.

3 . The display apparatus as claimed in claim 1 , wherein the first sub-pixel electrode further comprises a third sub-segment, the third sub-segment is connected with the first main segment, and the third sub-segment is located between the first sub-segment and the second sub-segment.

4 . The display apparatus as claimed in claim 3 , wherein, the third sub-segment has a curved shaped edge.

5 . The display apparatus as claimed in claim 3 , wherein the third sub-segment extends along a fifth direction and the fifth direction is different from the first direction.

6 . The display apparatus as claimed in claim 5 , wherein the fifth direction is the same as or different from the second direction.

7 . The display apparatus as claimed in claim 5 , wherein the fifth direction is the same as or different from the third direction.

8 . The display apparatus as claimed in claim 1 , wherein the pixel unit further comprises a third sub-pixel electrode disposed adjacent to the second sub-pixel electrode, wherein the first sub-pixel electrode corresponds to a first sub-pixel region, the second sub-pixel electrode corresponds to a second sub-pixel region, the third sub-pixel electrode corresponds to a third sub-pixel region, and areas of the first sub-pixel region, the second sub-pixel region, and the third sub-pixel region are substantially equal.

9 . The display apparatus as claimed in claim 8 , further comprising a support partially overlapped with the first sub-pixel region.

10 . The display apparatus as claimed in claim 8 , further comprising a support partially overlapped with the first sub-pixel region and the second sub-pixel region.

11 . The display apparatus as claimed in claim 10 , wherein an area in which the support is overlapped with the first sub-pixel region is greater than an area in which the support is overlapped with the second sub-pixel region.

12 . The display apparatus as claimed in claim 9 , wherein the shape of the support is oval-shaped, circular-shaped, or cross-shaped.

13 . The display apparatus as claimed in claim 9 , further comprising a light shielding layer, the light shielding layer comprises a protrusion part, wherein the support is disposed to be overlapped with the protrusion part.

14 . The display apparatus as claimed in claim 1 , wherein the pixel unit further comprises a third sub-pixel electrode disposed adjacent to the second sub-pixel electrode, wherein the first sub-pixel electrode corresponds to a first sub-pixel region, the second sub-pixel electrode corresponds to a second sub-pixel region, the third sub-pixel electrode corresponds to a third sub-pixel region, an area of the third sub-pixel region is smaller than or equal to an area of the second sub-pixel region, and the area of the second sub-pixel region or the area of the third sub-pixel region is smaller than an area of the first sub-pixel region.

15 . The display apparatus as claimed in claim 1 , wherein a number of the first main segment of the first sub-pixel electrode is different from a number of the second main segment of the second sub-pixel electrode.

16 . The display apparatus as claimed in claim 1 , wherein the second sub-segment has a curved shaped edge.

17 . The display apparatus as claimed in claim 1 , wherein the second direction is the same as or different from the third direction.

18 . The display apparatus as claimed in claim 1 , further comprising a plurality of scan lines, and a plurality of data lines, the scan lines and the data lines intersect each other, and segments of the data lines extend along the first direction or extend along the fourth direction.

19 . The display apparatus as claimed in claim 18 , wherein at least one of the data lines forms a zigzag pattern.

20 . The display apparatus as claimed in claim 1 , wherein an angle is between the first direction and the second direction, the angle ranges from 140 degrees to 185 degrees.
