Abstract

A display panel includes a plurality of sub-pixels, scanning lines and data lines. The sub-pixels are disposed on a first substrate and include a plurality of rows and columns, and each sub-pixel of a first row of two adjoining rows is shifted by a predetermined distance along a first direction with respect to each sub-pixel of a second row of two adjoining rows. The scanning lines extend in the first direction and corresponding to the sub-pixels of the rows respectively. Each data line includes a plurality of first data segments and second data segments connected alternately. The first data segment extends along a second direction and partially overlaps the scanning line in a vertical direction. Each second data segment is disposed on one side of the scanning line, and at least a portion of the second data segments extends along a third direction different from the first and second directions.

Claims

a first substrate;

a plurality of sub-pixels disposed on the first substrate and arranged in an array having a plurality of rows and columns, the sub-pixels of each of the rows being arranged in a first direction, and the sub-pixels of each of the columns being arranged in a second direction, wherein the first direction and the second direction substantially intersect, and each of the sub-pixels of a first row of two adjoining rows is shifted by a predetermined distance along the first direction with respect to each of the sub-pixels of a second row of the two adjoining rows;

a plurality of scanning lines disposed on the first substrate, wherein the scanning lines extend along the first direction and are disposed corresponding to the sub-pixels of the rows respectively;

a plurality of data lines disposed on the first substrate and corresponding to the sub-pixels of the columns respectively, wherein the data lines and the scanning lines intersect, each of the data lines comprises a plurality of first data segments and a plurality of second data segments, each first data segment and each second data segment being alternately connected to one another, the first data segments extend along the second direction and partially overlap the scanning lines in a vertical direction, each of the second data segments is disposed on one side of one corresponding scanning line, at least a portion of the second data segments extend along a third direction different from the first direction and the second direction, the third direction and the second direction have an included angle greater than 0 degree and less than 90 degrees;

a second substrate disposed on the first substrate; and

a display medium layer interposed between the first substrate and the second substrate.

2. The display panel of claim 1, wherein each of the sub-pixels comprises at least one thin film transistor, a drain electrode connection pad and at least one pixel electrode, the thin film transistor includes agate electrode, a source electrode and a drain electrode, the gate electrode is connected to the scanning line, the source electrode is connected to the data line, the drain electrode connection pad is connected to the drain electrode, and the pixel electrode is connected to the drain electrode connection pad.

3. The display panel of claim 2, further comprising a plurality of light-shielding patterns extending along the first direction and corresponding to the scanning lines, wherein each of the light-shielding patterns is disposed on one of the first substrate and the second substrate.

4. The display panel of claim 3, wherein the light-shielding patterns are further corresponding to the second data segments and the drain electrode connection pads, and each of the light-shielding patterns overlap the corresponding scanning line, the corresponding second data segments and the corresponding drain electrode connection pads in the vertical direction.

5. The display panel of claim 4, wherein the light-shielding pattern disposed in the sub-pixel has a width in the second direction, a distance exists between two light-shielding patterns adjoining to the sub-pixel in the second direction, and a ratio of the width to the distance is substantially greater than 0 and less than or equal to 0.4.

6. The display panel of claim 5, wherein a sum of the width and the distance is substantially equal to a length of the sub-pixel in the second direction.

7. The display panel of claim 2, wherein each of the drain electrode connection pads has two side edges substantially parallel to the second data segment.

8. The display panel of claim 7, wherein each of the drain electrode connection pads has a parallelogram shape.

9. The display panel of claim 7, wherein each of the drain electrode connection pads has an elliptic shape.

10. The display panel of claim 1, wherein the predetermined distance is less than a width of the sub-pixel in the first direction.

11. The display panel of claim 1, wherein the predetermined distance is greater than 0 and less than or equal to half of a width of the sub-pixel in the first direction.

12. The display panel of claim 1, wherein each of the sub-pixels comprises a color filter layer disposed on one of the first substrate and the second substrate.

13. The display panel of claim 1, wherein the second data segments do not overlap the scanning lines in the vertical direction.

14. The display panel of claim 1, wherein a portion of the second data segments extend along the third direction, another portion of the second data segments extend along a fourth direction different from the first direction, the second direction and the third direction, and the fourth direction and the second direction have another included angle less than 0 degree and greater than −

90 degrees.
