10088690 · 2018-10-02 · ·

The conductive film has a wiring pattern which, with respect to the frequencies and intensities of moire obtained by applying a human visual response characteristic to the frequency information and intensity information of moire calculated from peak frequencies and peak intensities of the two-dimensional Fourier spectrums of the transmittance image data of the wiring pattern and the transmittance image data of a pixel array pattern, causes the sum of intensities of moire each corresponding to frequencies of moire falling within a frequency range predetermined depending on the visual response characteristic to be less than or equal to a predetermined value. The conductive film allows suppression of moire and significant improvement in visibility.
