Transparent conductive film roll and production method thereof, touch panel using the same, and non-contact surface resistance measuring device
Abstract:
A transparent conductive film roll which has a transparent conductive layer on at least one surface thereof and has an excellent distribution uniformity of surface resistance in longitudinal and lateral directions thereof wherein the distribution uniformity D of surface resistance defined by the following expression (1) is 0.2 or less when the surface resistance of the transparent conductive layer is measured at a total of 33 points within the film roll, and therefore, is suitable especially for a large panel, D=(Rmax−Rmin)/(Rmax+Rmin)  (1) where Rmax and Rmin represent the maximum and minimum values of 33 surface resistance measurement values.
