Problems solved by technology

However, if the thickness of the transparent conductive layer formed of a high-refractive index material increases, the reflection of external light at the interface between the transparent conductive layer and the substrate increases, so that the transmittance of the transparent conductive film decreases
Therefore, there is a problem that the quality of the display device may deteriorate

Abstract

Disclosed is a conductive optical element which comprises: a base having a surface; a structure composed of a plurality of conical projections or recesses that are arranged on the surface of the base at a fine pitch that is not more than the wavelength of visible light; and a transparent conductive film formed on the structure. The aspect ratio of the structure is 0.2-1.3 (inclusive), and the transparent conductive film has a surface following the shape of the structure. The average film thickness (Dm1) of the transparent conductive film at the tops of the structure is not more than 80 nm, and the surface resistivity of the transparent conductive film is within the range of 50-50 (inclusive).

Description

technical field [0001] The present invention relates to a conductive optical element, a touch panel, an information input device, a display device, a solar cell, and a master for manufacturing the conductive optical element. Specifically, the present invention relates to a conductive optical element provided with a transparent conductive film on one main surface of a base thereof. Background technique [0002] In recent years, resistive touch panels for inputting information have been provided on display devices such as liquid crystal display elements included in mobile devices and cellular phone devices. [0003] The resistive touch panel has a structure in which two transparent conductive films are disposed opposite with respect to a space formed of an insulating material such as acrylic resin therebetween. The transparent conductive film is used as an electrode of the touch panel and includes a substrate having transparency (for example, a polymer film) and a high refrac...
