Conductive film, display device having the same, and method of evaluating conductive film

A conductive film that is provided on a display unit of a display device, the conductive film comprising:

• a transparent substrate;
• and
• a conductive section that is formed on at least one surface of the transparent substrate and is formed of a plurality of thin metal lines,
• wherein the conductive section has a wiring pattern which is formed in a mesh shape by the plurality of thin metal lines and in which a plurality of opening portions is arranged, and
• wherein regarding the wiring pattern, normalized spectrum intensities of spectrum peaks of an entire image of the wiring pattern, which is obtained by performing two-dimensional Fourier transform on transmittance image data of the entire image, are calculated, spectra, which have the normalized spectrum intensities equal to or greater than a specified value, are extracted, angles, each of which is formed between one coordinate axis of two-dimensional Fourier coordinates and a straight line connecting coordinates of each extracted spectrum and an origin of the two-dimensional Fourier coordinates, are calculated in units of a specific angle for each extracted spectrum, intensity differences, each of which is obtained from a maximum value and a minimum value of the normalized spectrum intensity for each angle, are calculated, at all points of the extracted spectrum by oscillating the angle by each unit of the specific angle, with respect to the extracted spectrum, one or more clusters of bars, which indicate frequencies of a histogram at an average value or more of the intensity difference in a case where the histogram is a histogram of the intensity differences at all the points, are isolated from the other cluster, and in a case where a second sample standard deviation indicating a variation of first sample standard deviations, each of which indicates a variation of the normalized spectrum intensities at a single angle, in all angular directions is calculated as a quantitative value of the wiring pattern, the quantitative value is in a specific numerical value range.
