An optical film to be arranged on a display surface is adapted so as to allow uniform application of an interlayer filler and thus also is applicable to an image display device equipped with a front plate. Preferably, such optical film is for use in an image display device. The optical film is adapted so that a relationship of the following formula (1) is satisfied:&#x2264;0.2+1.8&#x2003;&#x2003;(1),

Optical film, image display device, and method for producing image display device

Provided are a double-sided transparent conductive film which has blocking resistance and a low reflectance, and is inhibited from scattering reflected light to exhibit good visibility; a roll thereof; and a touch panel. The double-sided transparent conductive film of the present invention includes a base material film with an optical adjusting layer laminate and a transparent conductive layer formed in this order on each of both sides, the optical adjusting layer laminate including two or more optical adjusting layers, wherein the optical adjusting layers have different refractive indexes in each of the optical adjusting layer laminates, an anti-blocking layer containing particles is formed between the base material film and at least one of the optical adjusting layer laminates, the anti-blocking layer includes a flat portion, and a protrusion portion resulting from the particles, a value obtained by subtracting a value of a thickness of the flat portion of the anti-blocking layer from a value of a mode diameter of the particles is larger than a value of a thickness of the optical adjusting layer laminate, and the optical adjusting layer laminates each have a thickness of not less than 60 nm and not more than 250 nm.

Double-sided transparent conductive film and touch panel

A double-sided transparent conductive film including a base material film, having an anti-blocking layer, an optical adjusting layer and a transparent conductive layer formed in this order on each of both sides of the base material film, wherein an anti-blocking layer containing particles is formed at least one of: a location between the base material film and one optical adjusting layer; and a location between the base material film and the other optical adjusting layer, the anti-blocking layer has a flat portion and protrusion portions caused by the particles, and a value obtained by subtracting a thickness of the flat portion of the anti-blocking layer from a mode diameter of the particles is larger than a thickness of the optical adjusting layer.

Provided is a transparent conductive film including a hard coat layer having sufficient hardness, a superior abrasion resistance, and a superior soil resistance; also, provided are an electronic device and a touch panel using the transparent conductive film. A transparent conductive filmincludes a transparent film base, a transparent conductive layer, and a hard coat layer, wherein the hard coat layeris formed of a composition for forming hard coat containing the component (A): a curable compound including at least one of an acrylate group and a methacrylate group; the component (B): a reactive fluorine-containing compound; and the component (C): a reactive silicon-containing compound.

The present invention provides a hard-coated antiglare film that has an extremely low haze value, superior anti-fluorescent lamp glare properties, and anti-face glare properties, and can improve the depth of black in black display by preventing white blur from occurring. The hard-coated antiglare film: including a transparent plastic film substrate; and a hard-coating antiglare layer containing fine particles, and has a total haze value in a range of 0% to 5%. The number Nof convexities and the number Nof convexities satisfy the relationship 0.4&#x2266;N/N&#x2266;0.8. And the number of convexities in which line segments of portions of the mean line that cross the convexities each have a length of 50 &#x3bc;m or shorter, among convexities the exceed a second standard line that is parallel with the mean line and is located at a height of 0.2 &#x3bc;m, is 10 or less.
