Abstract

In the conductive film, a plurality of thin metal lines has a wavy wiring pattern in which a plurality of thin metal lines is formed as wavy lines, of which amplitudes are equal to or less than an amplitude threshold value, so as to have irregularity. The plurality of thin metal lines constitutes a typical wiring pattern which allows an indicator of evaluation of moirés to be equal to or less than an evaluation threshold value. Here, from at least one point of view, in frequencies and intensities of moirés each calculated for each color from first and second peak frequencies and first and second peak intensities of 2DFFT spectra of transmittance image data of a regular polygonal wiring pattern and luminance image data of a pixel array pattern of each color at the time of lighting up for each single color, the indicator of evaluation of moiré is calculated from evaluation values of moirés of the respective colors obtained by applying human visual response characteristics in accordance with an observation distance to intensities of the moirés equal to or greater than an intensity threshold value among intensities of the moirés at frequencies of moirés equal to or less than a frequency threshold value.
