<p>PURPOSE:To constitute a laminated film by specifying transmittance of light rays and a haze value, respectively, and forming a transparent and electrically conductive thin film on one of faces of the film where mean roughness on its center line is specified, and prevent sticking by using such a laminated film for transparent touch panel. CONSTITUTION:A laminated film is set to have transmittance of light rays at 80% or more, a haze value at 20% or less and mean roughness on the center line of one of faces of the film within a range of 0.05 to 5.0mum respectively, and is constituted by forming a transparent and electrically conductive thin film on said one face. The laminated film is used on at least one of faces of a transparent touch panel. On the other hand, the transparent touch panel has both upper and lower transparent sheets 1, 2 on each of which a transparent and electrically conductive thin film 3 is provided. Further, dot spacers 4 are formed between both the upper and lower transparent sheets 1, 2, and a support plate 5 is provided on the opposite face of the lower transparent sheet 2. In this case, a roughened surface 6 is formed on both the upper and lower transparent sheets 1, 2, and the transparent and electrically conductive thin film is formed on the roughened surfaces.</p> |
