PROBLEM TO BE SOLVED: To provide a conductive film having such a wiring pattern that can inhibit development of moire, can significantly improve visibility, and can improve picture qualities to be robust without depending on display resolution or a display pixel structure, a display device including the conductive film, and an evaluation method of a conductive film.SOLUTION: Wiring patterns A, D are processed in the following manner: a transmittance image data of the whole image is subjected to two-dimensional Fourier transformation to obtain a spectrum having a normalized spectral intensity equal to or higher than a specified value; and an intensity difference is calculated from the maximum and minimum in the normalized spectral intensity by each specific angle unit to obtain histograms C, F of intensity differences. In the histogram C, F, at least one block of columns representing frequencies equal to or greater than the average of the intensity differences is present as isolated from other blocks. The obtained spectra are further subjected to processes of calculating a first sample standard deviation in the variance of the normalized spectral intensity for one angle and of calculating a second sample standard deviation representing the variance of the first sample standard deviation for the whole angle directions; and the calculated second sample standard deviation is regarded as a quantitative value of the wiring pattern. The quantitative value is within a specific numerical range.SELECTED DRAWING: Figure 12 |
