## Abstract

A display device including: a display driving module including a display panel; a cover window including a central portion overlapping the display driving module and a curved portion surrounding the display driving module; and an outer structure disposed between the display driving module and the curved portion and surrounding the display driving module, wherein the outer structure is spaced apart from the display driving module.

## Claims

### Claim 1

A display device comprising:
a display driving module comprising a display panel;
a cover window comprising a central portion overlapping the display driving module and a curved portion surrounding the display driving module; and
an outer structure disposed between the display driving module and the curved portion and surrounding the display driving module,
wherein the outer structure is spaced apart from the display driving module.

### Claim 2 (depends on 1)

The display device of claim 1, wherein the outer structure directly contacts the curved portion.

### Claim 3 (depends on 1)

The display device of claim 1, wherein the outer structure is disposed away from an outer edge of the display driving module.

### Claim 4 (depends on 1)

The display device of claim 1, wherein the outer structure does not directly contact the display driving module.

### Claim 5 (depends on 1)

The display device of claim 1, wherein a lower surface of the outer structure is located on the same plane as a lower surface of the curved portion.

### Claim 6 (depends on 1)

The display device of claim 1, wherein the outer structure comprises a first portion contacting an inner surface of the curved portion and a second portion overlapped by a lower surface of the first portion.

### Claim 7 (depends on 6)

The display device of claim 6, wherein the second portion overlaps the first portion and the curved portion in a thickness direction of the display device.

### Claim 8 (depends on 6)

The display device of claim 6, wherein the second portion contacts the lower surface of the curved portion.

### Claim 9 (depends on 6)

The display device of claim 6, wherein an outermost surface of the curved portion protrudes beyond an outer surface of the second portion adjacent thereto.

### Claim 10 (depends on 9)

The display device of claim 9, further comprising a middle frame located opposite the cover window with the second portion of the outer structure interposed therebetween,
wherein the outer surface of the second portion is covered by the cover window or the middle frame.

### Claim 11 (depends on 10)

The display device of claim 10, further comprising a first coupling member disposed between the cover window and the middle frame, wherein
the middle frame comprises a middle sidewall facing the curved portion of the cover window, and
the first coupling member contacts a lower surface of the second portion, the lower surface of the curved portion, and an upper surface of the middle sidewall.

### Claim 12 (depends on 11)

The display device of claim 11, wherein the first coupling member comprises a first coupling portion contacting the second portion, a second coupling portion contacting the curved portion, and a step portion between the first coupling portion and the second coupling portion.

### Claim 13 (depends on 1)

The display device of claim 1, wherein the lower surface of the outer structure is higher than the lower surface of the curved portion.

### Claim 14 (depends on 13)

The display device of claim 13, further comprising a middle frame located below the cover window,
wherein the middle frame comprises a step portion overlapping the cover window in a horizontal direction.

### Claim 15 (depends on 14)

The display device of claim 14, wherein an upper surface of the step portion is higher than the lower surface of the curved portion.

### Claim 16 (depends on 14)

The display device of claim 14, further comprising a first coupling member disposed between the cover window and the middle frame,
wherein the first coupling member comprises a first coupling portion disposed on the step portion and a second coupling portion disposed on the lower surface of the curved portion.

### Claim 17 (depends on 1)

The display device of claim 1, wherein the display driving module further comprises a driving chip and a driving board disposed on an end of the display panel.

### Claim 18

A display device comprising:
a display driving module comprising a display panel;
a cover window comprising a central portion overlapping the display driving module and a curved portion surrounding the display driving module; and
an outer structure disposed between the display driving module and the curved portion and surrounding the display driving module,
wherein the outer structure overlaps the display driving module in a thickness direction of the display panel.

### Claim 19 (depends on 18)

The display device of claim 18, wherein the outer structure directly contacts the display driving module.

### Claim 20 (depends on 18)

The display device of claim 18, wherein
the display panel comprises a main area, a bending area disposed on a first side of the main area and a sub-area disposed on a second side of the bending area, and
the outer structure comprises a first portion disposed outside the bending area and a second portion disposed inside the bending area.

### Claim 21 (depends on 20)

The display device of claim 20, wherein the outer structure further comprises a third portion covering the sub-area of the display panel.

### Claim 22 (depends on 21)
