Abstract

A display device comprises a substrate, a first pixel on the substrate, the first pixel comprising a first subpixel, a second subpixel, and a third subpixel, a second pixel on the substrate, the second pixel comprising a fourth subpixel, a fifth subpixel, and a sixth subpixel, first, second, third and fourth power supply lines extending in one direction and respectively coupled to the first, third, fifth, and sixth subpixels, and fifth and sixth power supply lines crossing the first, second, third, and fourth power supply lines and respectively coupled to the fourth and second subpixels.

First claim

What is claimed is:

1. A display device comprising:
a substrate;
a first pixel on the substrate, the first pixel comprising a first subpixel, a second subpixel, and a third subpixel;
a second pixel on the substrate, the second pixel comprising a fourth subpixel, a fifth subpixel, and a sixth subpixel;
first, second, third, and fourth power supply lines extending in one direction and respectively coupled to the first, third, fifth, and sixth subpixels; and
fifth and sixth power supply lines crossing the first, second, third, and fourth power supply lines and respectively coupled to the fourth and second subpixels.

2. The display device of claim 1 , further comprising:
a gate line coupled to the first and second pixels;
a data line crossing the gate line and coupled to the first and second pixels; and
a switching transistor coupled to the gate line and the data line.

3. The display device of claim 2 , wherein the gate line is coupled to the first, second, third, fourth, fifth, and sixth subpixels.

4. The display device of claim 2 , wherein the first, second, third, and fourth power supply lines are on a same layer as the data line.

5. The display device of claim 2 , wherein the fifth and sixth power supply lines are on a same layer as the gate line.

6. The display device of claim 1 , wherein the first subpixel is a red subpixel, the second subpixel is a green subpixel, and the third subpixel is a blue subpixel.

7. The display device of claim 1 , wherein the third subpixel has a larger area than the first subpixel and the second subpixel.

8. The display device of claim 1 , wherein the fourth subpixel is a red subpixel, the fifth subpixel is a green subpixel, and the sixth subpixel is a blue subpixel.

9. The display device of claim 1 , wherein the sixth subpixel has a larger area than the fourth subpixel and the fifth subpixel.

10. The display device of claim 1 , further comprising a pattern configured to couple the first power supply line to the fifth power supply line.

11. The display device of claim 10 , wherein the pattern is a part of a storage electrode of the fourth subpixel.

12. The display device of claim 1 , further comprising a pattern configured to couple the sixth power supply line to the third power supply line.

13. The display device of claim 12 , wherein the pattern is a part of a source electrode of a driving transistor of the second subpixel.
