Abstract

A display device includes a substrate including a plurality of pixels disposed in a display area of the substrate. A non-display area of the substrate is disposed adjacent to the display area. The display device further includes a plurality of gate lines and a plurality of data lines arranged in a matrix form in the display area on the substrate, at least one driver integrated circuit (IC) disposed in the non-display area on the substrate, and a plurality of data fan-out wirings disposed on the substrate and connecting the data lines and the at least one driver IC. Lengths of the data fan-out wirings vary, and the data lines overlap the gate lines more as the lengths of the corresponding data fan-out wirings decrease.

Claims (29)

1. A display device, comprising:

a substrate comprising a display area and a non-display area adjacent to the display area, a plurality of pixels being disposed on the display area;

a plurality of first lines disposed on the display area;

a plurality of second lines disposed on the display area, the plurality of second lines crossing the plurality of the first lines; and

a plurality of fan-out lines disposed on the substrate, the plurality of fan-out lines connecting the second lines and a driver;

wherein the second lines overlap the first lines more at crossing areas where the first and second lines cross as the lengths of the corresponding fan-out lines decrease,

wherein the second lines have the same widths at non-crossing areas where the first and second lines do not cross.

2. The display device of claim 1 , wherein a capacitance between the second lines and the first lines increases as the length of the corresponding fan-out lines decreases.

3. The display device of claim 1 , wherein the lengths of the fan-out lines are the same as a shortest distance between the driver and the corresponding second lines.

4. The display device of claim 1 , wherein the fan-out lines comprise:

a one fan-out line connected to a one second line of the plurality of second lines, wherein the length of the one fan-out line is a greatest length among the lengths of the fan-out lines; and

an another fan-out line connected to an another second line of the plurality of second lines, wherein the length of the another fan-out line is a smallest length among the lengths of the fan-out lines, and the another fan-out line is disposed near a center portion of the driver.

5. The display device of claim 4 , wherein the lengths of the plurality of fan-out lines decrease from the one fan-out line to the another fan-out line.

6. The display device of claim 4 , wherein a resistance of the plurality of fan-out lines decreases from the one fan-out line to the another fan-out line.

7. The display device of claim 4 , wherein the second lines overlap the first lines more from the one second line to the another second line.

8. The display device of claim 4 , wherein a capacitance between the second lines and the first lines increases from the one second line to the another second line.

9. The display device of claim 4 , wherein the one fan-out line is connected to an end portion of the driver.

10. The display device of claim 4 , wherein the another fan-out line is connected to the center portion of the driver.

11. The display device of claim 1 , further comprising:

an insulating layer disposed between the first lines and the second lines, wherein the insulating layer insulates the first lines from the second lines.

12. The display device of claim 1 , wherein the driver includes a plurality of driver ICs, and the plurality of driver ICs is arranged at a consistent interval.

13. The display device of claim 1 , wherein the widths of the portions of at least one of the second lines at the crossing area is greater than a width of a majority portion of the at least one of the second lines at the non-crossing area.

14. A display device, comprising:

a substrate comprising a display area and a non-display area adjacent to the display area, a plurality of pixels being disposed on the display area;

a plurality of first lines and second lines disposed on the display area;

a plurality of fan-out lines disposed on the substrate, the plurality of fan-out lines connecting the second lines and a driver;

wherein the second lines comprises overlap portion overlapping with the first lines and non-overlapping portions not overlapping the first lines,

wherein the second lines have more areas as the lengths of the corresponding fan-out lines decrease,

wherein the non-overlapping portions of the second lines have the same widths.
