Abstract

A display device includes a plurality of gate lines extending in a first direction, a plurality of data lines extending in a second direction, a plurality of sub-gate lines corresponding to the plurality of gate lines and extending in a first direction to be adjacent to a corresponding gate line of the plurality of gate lines, a gate driver configured to drive the plurality of gate lines, a data driver configured to drive the plurality of data lines, and a plurality of pixels arranged in a display area, where an end of each of the plurality of gate lines extends in the first direction from the gate driver is electrically connected to a center portion of a corresponding sub-gate line in the first direction.

Claims (43)

1. A display device comprising:

a plurality of gate lines extending substantially in a first direction;

a plurality of data lines extending substantially in a second direction;

a plurality of sub-gate lines corresponding to the plurality of gate lines and extending in the first direction, wherein each of the plurality of sub-gate lines is disposed adjacent to a corresponding gate line of the plurality of gate lines;

a gate driver configured to drive the plurality of gate lines;

a data driver configured to drive the plurality of data lines; and

a plurality of pixels arranged in a display area,

wherein an end of each of the plurality of gate lines, which extends from the gate driver in the first direction, is electrically connected to a center portion of a corresponding sub-gate line in the first direction, and

wherein the center portion of the corresponding sub-gate line is disposed in a center portion of the display.

2. The display device of claim 1 , wherein the plurality of gate lines is in a one-to-one correspondence with the plurality of sub-gate lines.

3. The display device of claim 2 , wherein the gate driver comprises:

a first gate driver disposed in a first side of the display area, wherein the first gate driver drives a first group of the plurality of gate lines; and

a second gate driver disposed in a second side of the display area, which is opposite to the first side of the display area, and facing the first gate driver, wherein the second gate driver drives a second group of the plurality of gate lines.

4. The display device of claim 3 , wherein

an end of a gate line in the first group of the plurality of gate lines, which extends in the first direction from the first gate driver, is electrically connected to the center portion of the corresponding sub-gate line in the first direction, and

an end of a gate line in the second group of the plurality of gate lines, which extends in an opposite direction to the first direction from the second gate driver, is electrically connected to the center portion of the corresponding sub-gate line in the first direction.

5. The display device of claim 4 , wherein each of the plurality of gate lines has a length substantially equal to a length of the corresponding sub-gate line in the display area.

6. The display device of claim 1 , wherein each of the plurality of gate lines corresponds to K sub-gate lines of the plurality of sub-gate lines, wherein K is a natural number greater than one.

7. The display device of claim 6 , wherein the gate driver comprises:

a first gate driver configured to drive a first group of the plurality of gate lines; and

a second gate driver configured to drive a second group of the plurality of gate lines.

8. The display device of claim 7 , wherein

the first and second gate drivers and the data driver are arranged in a side of the display area along the first direction, and

the first and second gate drivers are disposed at opposing sides of the data driver.

9. The display device of claim 8 , further comprising:

a plurality of main gate lines corresponding to the plurality of sub-gate lines, respectively, and extending in the first direction, wherein each of the plurality of main gate lines is adjacent to a corresponding sub-gate line,

wherein the plurality of main gate lines are grouped into a first group and a second group,

each of the plurality of main gate lines in the first group electrically connects an end of a corresponding gate line in the first group of the plurality of gate lines, which extends in the second direction from the first gate driver, to the K sub-gate lines corresponding thereto, and

each of the plurality of main gate lines in the second group electrically connects an end of a corresponding gate line in the second group of the plurality of gate lines, which extends in the second direction from the second gate driver, to the K sub-gate lines corresponding thereto.

10. The display device of claim 9 , wherein the K sub-gate lines are arranged adjacent to each other.

11. The display device of claim 9 , wherein

a gate line in the first group of the plurality of gate lines is connected to corresponding K sub-gate lines of odd-numbered sub-gate lines of the plurality of sub-gate lines through the corresponding main gate line, and

a gate line in the second group of the plurality of gate lines is connected to corresponding K sub-gate lines of even-numbered sub-gate lines of the plurality of sub-gate lines through the corresponding main gate line.

12. The display device of claim 9 , wherein

each of the plurality of main gate lines is disposed substantially parallel to the corresponding sub-gate line, and

each of the plurality of main gate lines has a length substantially equal to a length of the corresponding sub-gate line in the first direction.

13. A method of manufacturing a display device, the method comprising:

providing a plurality of gate lines on a display panel of the display device, wherein the plurality of gate lines extends from a gate driver of the display device substantially in a first direction;

providing a plurality of data lines on the display panel, wherein the plurality of data lines extends from a data driver of the display device substantially in a second direction;

providing a plurality of sub-gate lines corresponding to the plurality of gate lines and extending in the first direction on the display panel, wherein each of the plurality of sub-gate lines is disposed adjacent to a corresponding gate line of the plurality of gate lines; and

providing a plurality of pixels in a display area of the display panel,

wherein an end of each of the plurality of gate lines, which extends from the gate driver in the first direction, is electrically connected to a center portion of a corresponding sub-gate line in the first direction, and

wherein the center portion of the corresponding sub-gate line is disposed in a center portion of the display area.
