Title:
TRANSPARENT CONDUCTIVE FILM, PRODUCTION METHOD OF TRANSPARENT CONDUCTIVE FILM, TOUCH PANEL AND DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP2015005495
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a transparent conductive film with which both visibility and reduction of resistance are achieved by specifying a surface configuration of a metal thin wire, and which is suitably used for a touch panel and a display device.SOLUTION: In a transparent conductive film 10 comprising a transparent base 12 and a metal wiring part 14 formed on the transparent base 12, a metal thin wire 24 constituting an electrode part 18 of the metal wiring part 14 has a surface configuration satisfying Ra/Sm>0.01 μm and having a metal volume ratio of 35% or more. Here, Ra represents arithmetic mean roughness that is not more than thickness of the metal wiring at the measurement point of the surface roughness, and the unit thereof is μm, and Sm represents the mean spacing of profile irregularities, the spacing being not less than 0.01 μm.
