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 (20)

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 which is constituted of a plurality of metal lines 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;

wherein the first electrode is formed on a detection area of the first substrate, the second electrode is formed on a detection area of the second substrate, and

wherein the plurality of metal lines of the first electrode and the plurality of metal lines of the second electrode are black in color;

wherein the display panel is a liquid crystal display panel which excludes a polarizing plate;

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

wherein the resin film constitutes a second polarizing plate.

2. 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 which is constituted of a plurality of metal lines 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;

wherein the first electrode is formed on a detection area of the first substrate, the second electrode is formed on a detection area of the second substrate, and

wherein the plurality of metal lines of the first electrode and the plurality of metal lines of the second electrode are black in color;

wherein the resin film constitutes a circular polarizing plate.

3. A display device with a touch panel according to any one of claims 1 and 2 , wherein a cushion layer which is softer than the resin film is further interposed between the resin film and the touch panel.

4. A display device with a touch panel according to any one of claims 1 and 2 , wherein an air cushion layer 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 and 2 , wherein a cushion layer which is softer than the resin film is further interposed between the display panel and the touch panel.

6. A display device with a touch panel according to any one of claims 1 and 2 , wherein an air cushion layer is further interposed between the display panel and the touch panel.
