Transparent conductive film and touch panel
First Claim
1. A transparent conductive film comprising:
- a polymer film, a transparent conductive layer formed on the polymer film, and consisting of one of a zinc oxide system and a tin oxide system, and a covering layer formed on the transparent conductive layer and consisting mainly of at least one material selected from the group consisting of C, CNx, BNx, BxC and SiCx.

Abstract
A transparent conductive film has a polymer film 4 and a transparent conductive layer 5 formed on the polymer film 4. The transparent conductive layer includes indium oxide, a zinc oxide system and a tin oxide system. A covering layer 9, made of material different from that of the transparent conductive layer 5, is formed on the transparent conductive layer 5. A touch panel is provided with the transparent conductive film as its upper electrode 6A or lower electrode. The surface of the transparent conductive layer is covered with the covering layer, so that physical or chemical stresses generated during the input to the touch panel do not affect transparent conductive layer directly, thus preventing damages and delamination of the transparent conductive layer. Furthermore, the covering layer formed on the transparent conductive layer improves the strength of the transparent conductive film, thereby enhancing a resistance to wear.
