Abstract

A display device includes a display panel having an active area in which sub-pixels formed at crossing regions of data lines extending in a first direction and gate lines extending in a second direction crossing the first direction are arranged, and a non-active area outside of the active area. A driver supplies a drive signal to the gate and data lines in the display panel. Data links are extended in the first direction from the driver to supply a data signal to the data lines. Gate links are extended out from the driver and extended up to the active area in the first direction from the non-active area between the driver and the active area so as to supply a gate signal to the gate lines extending in the second direction. Accordingly, it is possible to reduce or minimize the area of the non-active area and/or to improve an aperture ratio.

Claims

1. A display device comprising:

a display panel having an active area in which sub-pixels formed at crossing regions of data lines extending in a first direction and gate lines extending in a second direction crossing the first direction are arranged, and a non-active area outside of the active area;

data links extending in the first direction from the driver to supply a data signal to the data lines; and

gate links extending out from the driver and extended up to the active area in the first direction from the non-active area between the driver and the active area so as to supply a gate signal to the gate lines extending in the second direction.

2. The display device according to claim 1, wherein the gate links formed in the non-active area are formed only in the non-active area between the driver and the active area, and the gate links are formed on a same line with the data lines in the active area.

3. The display device according to claim 2, wherein a gate link of the gate links and a corresponding data line of the data lines are formed to overlap with each other with an insulating layer interposed therebetween.

4. The display device according to claim 2, wherein a gate link of the gate links is extended up to a corresponding gate line of the gate lines to be electrically connected thereto.

5. The display device according to claim 1, wherein the gate links form pairs of gate links, and each of the pairs of gate links are formed on a same line in the active area.

6. The display device according to claim 5, wherein paired gate links in each of the pairs of gate links are formed to overlap with each other with an insulating layer interposed therebetween.

7. The display device according to claim 5, wherein a gate link of the gate links is extended up to a corresponding gate line of the gate lines to be electrically connected thereto.

8. The display device according to claim 5, wherein two pairs of the pairs of gate links are formed with two sub-pixels of the sub-pixels extending in the second direction interposed therebetween, except at first side sub-pixels of the sub-pixels positioned at a first outermost side of the active area, and that only one gate link of the gate links is formed at a side portion of second side sub-pixels of the sub-pixels positioned at a second outermost side of the active area.

9. The display device according to claim 5, wherein the data lines form pairs of data lines, and each of the pairs of data lines are formed on a same line in the active area.

10. The display device according to claim 9, wherein paired data lines in each of the pairs of data lines are formed to overlap with each other with an insulating layer interposed therebetween.

11. The display device according to claim 9, wherein only one data line of the data lines is formed at a side portion of the sub-pixels positioned at an outermost side of the active area, and two pairs of the pairs of data lines are formed with two sub-pixels of the sub-pixels extending in the second direction interposed therebetween, except at side sub-pixels of the sub-pixels positioned at the outermost side of the active area.
