Abstract

The present invention provides a display device with a touch panel which gives a user excellent touch feeling. A display device with a touch panel includes: a touch panel which includes a first substrate, a second substrate arranged to face the first substrate in an opposed manner with a gap formed therebetween, a first electrode which is constituted of a plurality of metal lines formed on a surface of the first substrate which faces the second substrate, and a second electrode formed on a surface of the second substrate which faces the first substrate; a display panel which is mounted on the second substrate on a side opposite to the first substrate; and a resin film which is adhered to the first substrate on a side opposite to the second substrate.

Claims

1. A display device with a touch panel comprising:

a touch panel which includes a first substrate, a second substrate arranged to face the first substrate in an opposed manner with a gap formed therebetween, a first electrode which is constituted of a plurality of metal lines formed on a surface of the first substrate which faces the second substrate, and a second electrode formed on a surface of the second substrate which faces the first substrate;

a display panel which is mounted on the second substrate on a side opposite to the first substrate; and

a resin film which is adhered to the first substrate on a side opposite to the second substrate.

2. A display device with a touch panel according to claim 1, wherein the display panel is a liquid crystal display panel which excludes a polarizing plate,

a first polarizing plate is adhered to a surface of the display panel opposite to the second substrate, and

the resin film constitutes a second polarizing plate.

3. A display device with a touch panel according to claim 1, wherein the resin film constitutes a circular polarizing plate.

4. A display device with a touch panel according to any one of claims 1 to 3, wherein a cushion layer which is softer than the resin film is further interposed between the resin film and the touch panel.

5. A display device with a touch panel according to any one of claims 1 to 3, wherein an air cushion layer is further interposed between the resin film and the touch panel.

6. A display device with a touch panel according to any one of claims 1 to 3, wherein a cushion layer which is softer than the resin film is further interposed between the display panel and the touch panel.

7. A display device with a touch panel according to any one of claims 1 to 3, wherein an air cushion layer is further interposed between the display panel and the touch panel.
