## Abstract

Provided is a display device, comprising: a display panel; a frame that holds the display panel; and an adhesive member to adhesively fix the display panel and the frame to each other. The adhesive member includes a base material, a first adhesive layer disposed on a surface on the display panel side of the base material, and a second adhesive layer disposed on a surface on a frame side of the base material. In planar view, the first adhesive layer and the second adhesive layer are disposed in at least a part of the adhesive member so as not to overlap each other, and a clearance is formed between the first adhesive layer and the second adhesive layer.

## Claims

### Claim 1

A display device, comprising:
a display panel;
a frame that holds the display panel; and
an adhesive member to adhesively fix the display panel and the frame to each other, wherein
the adhesive member includes a base material, a first adhesive layer disposed on a surface on the display panel side of the base material, and a second adhesive layer disposed on a surface on a frame side of the base material, and
in planar view, the first adhesive layer and the second adhesive layer are disposed in at least a part of the adhesive member so as not to overlap each other, and a clearance is formed between the first adhesive layer and the second adhesive layer,
wherein the second adhesive layer attaches to a surface of the frame, and
the first adhesive layer at least partially overlaps the surface of the frame in planar view.

### Claim 2 (depends on 1)

The display device according to claim 1, wherein in planar view, the first adhesive layer and the second adhesive layer are disposed alternately in an extending. direction of the base material.

### Claim 3 (depends on 1)

The display device according to claim 1, wherein in planar view, the first adhesive layer and the second adhesive layer are disposed side by side in a direction perpendicular to an extending direction of the base material.

### Claim 4 (depends on 1)

The display device according to claim 1, wherein in planar view, one of the first adhesive layer and the second adhesive layer is formed in a comb teeth shape, and the other is disposed in regions between comb teeth.

### Claim 5 (depends on 1)

The display device according to claim 1, wherein in planar view, the first adhesive layer and the second adhesive layer are disposed in matrix.

### Claim 6 (depends on 1)

The display device according to claim 1, wherein in a region corresponding to the clearance in the base material, a cutout portion is formed.

### Claim 7 (depends on 1)

The display device according to claim 1, further comprising a driver IC that drives a signal line disposed in the display panel, wherein
the first adhesive layer is disposed in a layer under the driver IC.

### Claim 8 (depends on 1)

The display device according to claim 1, wherein
the base material is made of polycarbonate or polyethylene terephthalate, and
the first adhesive layer and the second adhesive layer are each made of a double-sided adhesive tape.

### Claim 9 (depends on 1)

The display device according to claim 1, wherein all area of the first adhesive layer overlaps the surface of the frame in planar view.
