abstract |
This invention provides the board | substrate which comprised ITO with low ITO pattern visibility by the method with little cost and process load using simple techniques, such as application | coating or printing. An object of the present invention is to provide a touch panel member using the substrate. The present invention provides (I) ITO (Indium Tin Oxide) thin film, (II) a film thickness of 0.01 μm to 0.4 μm, and a film thickness of 0.01 μm to 10 μm from the upper surface of the transparent base substrate. Provided is a substrate having a portion where thin films are laminated in the order of silicon thin film (III). |
