Abstract

In an aspect, a display device comprising a panel having a circular surface and a pad unit which is disposed adjacent to an outer circumference of the panel and receives an external signal, wherein the pad unit is divided into a plurality of sub-pads, and the sub-pads are separated from each other is provided.

First claim

What is claimed is:

1. A display device comprising:
a panel having a circular surface;
a pad unit which is disposed adjacent to an outer circumference of the panel and receives a driving signal for the panel; and
a base film on which a semiconductor chip is mounted, wherein the base film comprises a plurality of separate sub-films, and each of the sub-films comprises bumps connected to one of the sub-pads,
wherein the driving signal includes gate signals and data signals,
wherein the pad unit is divided into a plurality of sub-pads, and the sub-pads are separated from each other.

2. The display device of claim 1 , wherein the bumps are formed to correspond to each of the sub-pads.

3. The display device of claim 1 , wherein the sub-pads are separated by substantially equal distances.

4. The display device of claim 1 , wherein the sub-pads are symmetrical with respect to a virtual line that connects a central point on the surface of the panel and a point on a side of the panel.

5. The display device of claim 1 , wherein the sub-pads extend in a direction and have equal lengths.

6. The display device of claim 1 , wherein the panel comprises a display area in which display elements are located and a non-display area which surrounds the display area, wherein the pad unit is formed in the non-display area.

7. A display device comprising:
a panel having a circular surface;
a pad unit which is disposed adjacent to an outer circumference of the panel and receives a driving signal for the panel; and
a base film on which a semiconductor chip is mounted, wherein the base film comprises a plurality of separate sub-films, and each of the sub-films comprises bumps connected to one of the sub-pads,
wherein the driving signal includes gate signals and data signals,
wherein the pad unit is divided into a plurality of sub-pads, and the sub-pads are arranged along a side of the panel to be separated from each other.

8. The display device of claim 7 , wherein each of the sub-pads comprise a plurality of unit sub-pads, wherein each of the unit sub-pads forms a step difference with an adjacent unit sub-pad.

9. The display device of claim 7 , wherein the sub-pads are symmetrical with respect to a virtual line that connects a central point on the surface of the panel and a point on the side of the panel.

10. The display device of claim 7 , wherein the bumps are formed to correspond to each of the sub-pads.

11. The display device of claim 7 , wherein each of the sub-films has a side rounded to correspond to the side of the panel.

12. The display device of claim 7 , wherein the panel comprises a display area in which display elements are located and a non-display area which surrounds the display area, wherein the pad unit is formed in the non-display area.

13. A display device comprising:
a panel having a circular surface;
a pad unit which is disposed adjacent to an outer circumference of the panel and receives a driving signal for the panel; and
a film on which a semiconductor chip is mounted, wherein the film comprises a plurality of separate sub-films, and each of the sub-films comprises bumps connected to one of the sub-pads,
wherein the driving signal includes gate signals and data signals,
wherein the pad unit is divided into a plurality of sub-pads which are arranged along a side of the panel, wherein the sub-pads are separated from each other, and the sub-pads and the side of the panel are separated by equal distances.

14. The display device of claim 13 , wherein each of the sub-pads comprise a plurality of unit sub-pads, wherein each of the unit sub-pads is placed toward a central point on the surface of the panel.

15. The display device of claim 13 , wherein the bumps are formed to correspond to each of the sub-pads.

16. The display device of claim 13 , wherein each of the sub-films has a side rounded to correspond to the side of the panel.

17. The display device of claim 13 , wherein the panel comprises a display area in which display elements are located and a non-display area which surrounds the display area, wherein the pad unit is formed in the non-display area.
