Abstract

A display panel is provided. The display panel includes a first sub-pixel row including a plurality of sub-pixels electrically connecting to a scan line; and a second sub-pixel row including a plurality of sub-pixels, wherein the scan line overlaps with an area of the sub-pixels of the second sub-pixel row, and the scan line overlaps with an edge of a first sub-pixel of the sub-pixels of the first sub-pixel row, wherein the edge is adjacent to a driving transistor of the first sub-pixel.

Claims

a first sub-pixel row comprising a plurality of sub-pixels electrically connecting to a scan line; and

a second sub-pixel row comprising a plurality of sub-pixels, wherein the scan line overlaps with an area of the sub-pixels of the second sub-pixel row, and the scan line overlaps with an edge of a first sub-pixel of the sub-pixels of the first sub-pixel row, wherein the edge is adjacent to a driving transistor of the first sub-pixel.

2. The display panel as claimed in claim 1, wherein the scan line overlaps with an area of a pixel electrode of the sub-pixels of the second sub-pixel row.

3. The display panel as claimed in claim 2, wherein the scan line overlaps with an edge of a pixel electrode of the first sub-pixel.

4. The display panel as claimed in claim 1, wherein the sub-pixels of the first sub-pixel row and the second sub-pixel row are in a shape of a rectangle, rhombus or polygon.

5. The display panel as claimed in claim 1, wherein the sub-pixels of the first sub-pixel row and the second sub-pixel row comprise one of red, blue or green sub-pixels or a combination thereof.

6. The display panel as claimed in claim 1, wherein the area of the sub-pixels of the second sub-pixel row where the scan line overlaps with, corresponds to a liquid crystal shadow area.

7. The display panel as claimed in claim 1, wherein the sub-pixels of the second sub-pixel row are respectively disposed between the sub-pixels of the first sub-pixel row such that the sub-pixels of the first sub-pixel row and the sub-pixels of the second sub-pixel row are in a staggered arrangement.

8. The display panel as claimed in claim 1, further comprising a plurality of first data lines overlaps with an area of the sub-pixels of the first sub-pixel row.

9. The display panel as claimed in claim 8, wherein the area of the sub-pixels of the first sub-pixel row where the first data lines overlaps with, corresponds to a liquid crystal shadow area.

10. The display panel as claimed in claim 8, further comprising a plurality of second data lines overlaps with an area of the sub-pixels of the second sub-pixel row.

11. The display panel as claimed in claim 10, wherein the area of the sub-pixels of the second sub-pixel row where the second data lines overlaps with, corresponds to a liquid crystal shadow area.
