CONDUCTIVE FILM, DISPLAY DEVICE PROVIDED WITH SAME, AND METHOD FOR EVALUATING CONDUCTIVE FILM

摘要

The conductive film includes a transparent substrate and a conductive portion having a wiring pattern, in which when the wiring pattern is observed from at least one visual point, with respect to frequencies and intensities of moires which are calculated respectively from peak frequencies and peak intensities of predetermined data_and peak frequencies and peak intensities of another predetermined data, an evaluation index of moire, which is calculated from evaluation values of moires obtained by applying visual response characteristics of a human being to the intensities of the moires according to an observation distance at the frequencies of the respective moires that are equal to or lower than the maximum frequency of moire specified according to display resolution of the display unit, is equal to or less than a predetermined value.
