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 that is used for, for example, a touch panel or the like, can suppress coloration of transmitted light, and has excellent total light transmittance. Background technique [0002] Currently, as a device that can input information by directly touching the image display portion, a touch panel is sometimes used. The touch panel is configured by arranging input devices for transmitting light on various displays such as liquid crystal display devices and CRTs. Representative forms of touch panels include: a resistive film type touch panel in which two transparent electrode substrates are arranged such that their transparent electrode layers face each other; and a touch panel that uses the current capacity generated between the transparent electrode layer and the finger Variable capacitance type touch panel. [0003] As the transparent electrode substrate of a resistive touch panel or a capacitive touc...
