Abstract

An input-cable display device is provided including a first substrate on which a pair of electrodes that drive a liquid crystal layer are provided; a second substrate wherein the liquid crystal layer is formed within an inner surface of the second substrate between the first substrate and the second substrate; a detection electrode and a dielectric film that are laminated on an outer surface of the second substrate; a detector; a light shielding film; and a color filter layer, wherein the pair of electrodes provided on the first substrate comprises a pixel electrode and a common electrode, and the light shielding film and the color filter layer are laminated on the inner surface of the second substrate.

Claims (14)

1. A display device comprising:

a first substrate including a pair of electrodes provided thereon, the pair of electrodes comprising a pixel electrode and a common electrode;

a second substrate opposed to the first substrate;

a liquid crystal layer provided between the first substrate and the second substrate;

a polarizer provided on an outer portion side of the second substrate, the outer portion side being opposite to a liquid crystal layer side of the second substrate;

a shield conductor provided between the polarizer and the liquid crystal layer;

a light shielding film; and

a color filter layer,

wherein an electric potential of the shield conductor is fixed, and

wherein the shield conductor, the light shielding film and the color filter layer are laminated on the liquid crystal layer side of the second substrate in order of the shield conductor, the light shielding film, and the color filter layer from the side of the second substrate toward the liquid crystal layer.

2. The display device according to claim 1 , wherein the shield conductor has translucency.

3. The display device according to claim 1 , wherein the pair of electrodes constitute a horizontal electric field mode structure.

4. The display device according to claim 1 , wherein the pair of electrodes are arranged on different layers of the first substrate.

5. The display device according to claim 1 , wherein the shield electrode has a sheet resistance of 1 kΩ/sq or below.
