Abstract

A display device includes a substrate. The substrate includes a front surface display portion. A first side surface display portion is bent from a first side of the front surface display portion. A second side surface display portion is bent from a second side of the front surface display portion. A corner display portion extends from the first side surface display portion and the second side surface display portion. The substrate has a through hole defined by the front surface display portion and the corner display portion.

First claim

What is claimed is:

1. A display device comprising:
a substrate,
wherein the substrate comprises:
a front surface display portion;
a first side surface display portion bent from a first side of the front surface display portion;
a second side surface display portion bent from a second side of the front surface display portion; and
a corner display portion extending from the first side surface display portion and the second side surface display portion, and
wherein the substrate has a through hole defined by the front surface display portion and the corner display portion, the through hole being spaced apart from a periphery of the substrate.

2. The display device of claim 1 , wherein the corner display portion comprises a first side surface corner display portion extending from the first side surface display portion, a second side surface corner display portion extending from the second side surface display portion, and a corner non-display portion between the first side surface corner display portion and the second side surface corner display portion.

3. The display device of claim 2 , wherein the corner non-display portion comprises a first folding portion bent and extending from the first side surface corner display portion and a second folding portion bent and extending from the first folding portion and the second side surface corner display portion, and
wherein at least a portion of the first folding portion is in direct contact with at least a portion of the second folding portion.

4. The display device of claim 3 , wherein the first folding portion and the second folding portion overlap one of the first side surface corner display portion and the second side surface corner display portion.

5. The display device of claim 2 , wherein the corner non-display portion does not comprise a pixel electrode.

6. The display device of claim 1 , wherein the front surface display portion has a rounded corner.

7. The display device of claim 6 , wherein the corner display portion has a round shape corresponding to a shape of the corner of the front surface display portion.

8. The display device of claim 1 , further comprising:
a plurality of pixels on the substrate and arranged in a matrix form;
a plurality of gate lines extending along a first direction and providing a gate signal to each of the plurality of pixels; and
a plurality of data lines extending along a second direction crossing the first direction and providing a data signal to each of the plurality of pixels.

9. The display device of claim 8 , wherein at least one of the plurality of data lines and the plurality of gate lines comprises a first divided wiring and a second divided wiring which are divided by the through hole, and comprises a bypass wiring which bypasses the through hole and connects the first divided wiring and the second divided wiring.

10. The display device of claim 9 , wherein the bypass wiring is disposed so that an insulating layer is disposed between the bypass wiring and each of the first and second divided wirings, and
the bypass wiring is connected to the first and second divided wirings through contact holes defined at the insulating layer.

11. The display device of claim 10 , wherein at least one of the contact holes is located at the front surface display portion.

12. The display device of claim 9 , further comprising a dummy wiring.

13. The display device of claim 8 , wherein at least one of the plurality of gate lines and the plurality of data lines is curved along a periphery of the through hole.

14. The display device of claim 8 , further comprising a gate driver arranged to apply a gate signal to the gate lines divided by the through hole.

15. The display device of claim 8 , further comprising a data driver arranged to apply a data signal to the data lines divided by the through hole.

16. The display device of claim 8 , further comprising a demultiplexer arranged to apply a data signal to the data lines divided by the through hole.
