Abstract

A transparent conductive film has a high-refractive index layer, a low-refractive index layer and a tin-doped indium oxide layer (ITO layer) which are laminated in order on a first main surface of a polyester film. The high-refractive index layer is composed of metal oxide particles and ultraviolet curing adhesives. When the wavelength is 400nm, the refractive index of the high-refractive index layer is 1.63-1.86, and the thickness of the high-refractive index layer is 40-90nm. When the wavelength is 400nm, the refractive index of the low-refractive index layer is 1.33-1.53, and the thickness of the low-refractive index layer is 10-50nm. When the wavelength is 400nm, the refractive index of the ITO layer is 1.85-2.35, and the thickness of the ITO layer is 5-50nm.

Description

technical field [0001] The present invention relates to a transparent conductive film which is used for, for example, a touch panel or the like, and which can suppress coloring of transmitted light and has excellent total light transmittance. Background technique [0002] Currently, a touch panel is sometimes used as a device capable of inputting information by directly touching an image display portion. This touch panel is configured by arranging an input device for transmitting light on various displays such as a liquid crystal display device and a CRT. Representative forms of touch panels include: a resistive touch panel in which two transparent electrode substrates are arranged so that their transparent electrode layers face each other; and a touch panel that utilizes the current capacity generated between the transparent electrode layer and a finger Varying electrostatic capacitive touch panel. [0003] As a transparent electrode substrate for a resistive film touch p...
