## Abstract

A display device includes a window member, a display panel, a first adhesive member, and a reinforcing member. The display panel is disposed below the window member. The first adhesive member is disposed between the window member and the display panel. The first adhesive member overlaps the display panel. The reinforcing member is disposed below the display panel such that the display panel is disposed between the window member and the reinforcing member. On a plane of the window member, a first minimum distance from an outermost portion of the window member to an outermost portion of the display panel is equal to a second minimum distance from the outermost portion of the window member to an outermost portion of the first adhesive member.

## Claims

### Claim 1

A display device comprising:
a window member;
a display panel disposed below the window member;
an input sensing unit disposed between the window member and the display panel;
a first adhesive member disposed between the input sensing unit and the display panel;
a second adhesive member disposed between the window member and the input sensing unit and contacting the window member and the input sensing unit; and
a reinforcing member disposed below the display panel,
wherein the display panel comprises:
a first display area;
a second display area and a third display area protruding from the first display area and spaced apart from each other,
wherein each of the second display area and the third display area protrudes from the first display area in a first direction,
wherein, on a plane of the window member, a first minimum distance from an outermost portion of the window member to an outermost portion of the display panel is equal to a second minimum distance from the outermost portion of the window member to an outermost portion of the first adhesive member,
wherein, on the plane of the window member, a third minimum distance from the outermost portion of the window member to an outermost portion of the input sensing device is less than the first minimum distance,
wherein, on the plane of the window member, a third minimum distance from the outermost portion of the window member to an outermost portion of the input sensing device is less than a first minimum distance,
wherein, on the plane of the window member, the second minimum is less than a fourth minimum distance from the outermost portion of the window member to an outermost portion of the second adhesive member,
wherein, on the plane of the window member, the second minimum distance is less than a fifth minimum distance from the outermost portion of the window member to an outermost portion of the reinforcing member, and
wherein, when viewed in a thickness direction of the window member, the outermost portion of the reinforcing member is spaced apart from the outermost portion of the window member and overlaps the window member.

### Claim 2 (depends on 1)

The display device of claim 1, the first minimum distance is less than the fourth minimum distance.

### Claim 3 (depends on 1)

The display device of claim 1, wherein:
wherein the display panel comprises:
a first non-bending area overlapping the first display area, the second display area, and third display area, and
a second non-bending area spaced apart from the first non-bending area; and
a bending area connecting the first non-bending area to the second non-bending area.

### Claim 4 (depends on 3)

The display device of claim 3, wherein an entire area of the first adhesive member entirely overlaps the first non-bending area and partially overlaps the second non-bending area.

### Claim 5 (depends on 3)

The display device of claim 3, wherein a plurality of display elements is disposed on the first non-bending area.

### Claim 6 (depends on 3)

The display device of claim 3, further comprising:
a protection member disposed between the display panel and the reinforcing member,
wherein the protection member comprises:
a first protection member disposed on the first non-bending area; and
a second protection member disposed on the second non-bending area, and
wherein an entire area of the reinforcing member entirely overlaps the first protection member.

### Claim 7 (depends on 6)

The display device of claim 6, wherein on the plane of the window member, the fifth minimum distance is greater than the first minimum distance.

### Claim 8 (depends on 6)

The display device of claim 6, wherein, on the plane of the window member, the fifth minimum distance is equal to or less than the first minimum distance.

### Claim 9 (depends on 1)

The display device of claim 1, wherein the reinforcing member comprises a metallic material.

### Claim 10 (depends on 6)

The display device of claim 6, wherein the protection member comprises a recess portion adjacent to a boundary between the first display area and the bending area.

### Claim 11 (depends on 10)

The display device of claim 10, wherein the outermost portion of the reinforcing member is overlapped with the recess portion.

### Claim 12 (depends on 10)

The display device of claim 10, wherein an inner side defining the recess portion is aligned with the outermost portion of the reinforcing member.

### Claim 13 (depends on 1)

The display device of claim 1, wherein, on the plane of the window member, the third minimum distance is less than the fourth minimum distance.
