Abstract:
A conductive film has a polygonal wiring pattern which allows an indicator of evaluation of noises to be equal to or less than an evaluation threshold value. Here, from at least one point of view, in frequencies and intensities of noises 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 combined wiring pattern including a random mesh pattern of a plurality of thin metal lines of a wiring portion and luminance image data of a pixel array pattern of each color at the time of lighting on for each single color, the indicator of evaluation of noise is calculated from evaluation values of noises of the respective colors obtained by applying human visual response characteristics in accordance with an observation distance to intensities of the noises equal to or greater than a first intensity threshold value among intensities of the noises at frequencies of noises equal to or less than a frequency threshold value defined by a display resolution of a display unit.
