An electroconductive film which is capable of inhibiting milkiness; and a touch panel and image display device that include the electroconductive film are provided. According to one aspect of the present invention, an electroconductive filmincluding at least an electroconductive part, wherein the electroconductive partincludes a light-transmitting resinand a plurality of electroconductive fibersplaced in the light-transmitting resin, and the diffused light reflectance (SCE) in a region of the electroconductive filmwhere the electroconductive partis present is 0.5% or less, is provided.

Electroconductive film, sensor, touch panel, and image display device

The present invention aims to provide a conductive layered body having excellent solvent resistance and scratch resistance as well as a low haze value and a significantly high light transmittance. The present invention relates to a conductive layered body including, as an outermost layer thereof, a conductive layer containing a conductive fibrous filler, wherein the conductive layered body has a Martens hardness of 150 to 3,000 N/mmas measured at an indentation depth of 100 nm from a surface, and a ratio, in atomic percentage, of a conductive material element constituting the conductive fibrous filler on an outermost surface-side surface of the conductive layer is 0.15 to 5.00 at %.

Electroconductive layered product, touch panel, and process for producing electroconductive layered product

One aspect of the present invention provides an electroconductive filmcomprising a light-transmitting base material, a plurality of light-transmitting electroconductive partsprovided on one surfaceA of the light-transmitting base material, and a nonconductive partlocated between the electroconductive parts, wherein each of the electroconductive partscontains a light-transmitting resinand an electroconductive fiberincorporated in the light-transmitting resin; the nonconductive partcontains a light-transmitting resin; and the surfaceA of the nonconductive parthas an arithmetic average roughness of 3 nm or more.

Provided is an antiglare film having a hard coat property, capable of highly suppressing generation of a rainbow interference pattern and interference fringes in display images, preventing white muddiness and scintillation of a display screen, while giving high contrast in a bright room and a dark room. The antiglare film includes an antiglare layer having an uneven form on its surface and formed on one face of a transparent substrate having an in-plane birefringence and a retardation of 3000 nm or higher. The antiglare layer contains silica fine particles, organic fine particles, and a binder resin. The silica particles include particles forming agglomerates to be contained coarsely and densely in the antiglare layer. The agglomerates are distributed densely around the organic fine particles, and some agglomerates adhere to surfaces of the organic particles and/or some silica particles are impregnated in the inside of the organic particles.
