Abstract

A display apparatus includes a display panel displaying an image thereon, a cover panel arranged facing the display panel across an air layer, and an electro-conductive material opening electrically and arranged on a surface of one of the display panel and the cover panel faced with the air layer.

Claims

1. A display apparatus, comprising:

a display panel displaying an image thereon;

a cover panel arranged facing the display panel across an air layer; and

an electro-conductive material opening electrically and arranged on a surface of one of the display panel and the cover panel faced with the air layer.

2. A display apparatus according to claim 1, wherein the cover panel comprises a touch panel for detecting a pressed position.

3. A display apparatus according to claim 1, wherein the electro-conductive material comprises one of an antistatic membrane and a conductive layer.

4. A display apparatus according to claim 1, wherein a surface resistance value of the electro-conductive material is equal to or lower than 1×

E12 Ω

/square.

5. A display apparatus according to claim 1, wherein a visible light transmittance of the electro-conductive material is equal to or higher than 95%.

6. A display apparatus according to claim 1, wherein a thickness of the electro-conductive material is equal to or smaller than 1 micron.

7. A display apparatus according to claim 1, wherein the electro-conductive material contains a nonionic-based surface active agent.

8. A display apparatus according to claim 1, wherein the electro-conductive material contains a metal oxide.

9. A display apparatus according to claim 8, wherein the metal oxide contains one of an indium oxide and a tin oxide.

10. A display apparatus according to claim 1, wherein the electro-conductive material contains a metal.

11. A display apparatus according to claim 1, further comprising:

a protection film for protecting the electro-conductive material on the surface of the electro-conductive material.

12. A display apparatus according to claim 1, wherein the display apparatus comprises a liquid crystal display apparatus.

13. An electronic device equipped with a display apparatus, comprising the display apparatus according to claim 1.

14. A method of manufacturing a display apparatus comprising a display panel for displaying an image thereon, the method comprising:

forming a nonionic-based surface active agent in a mist form;
