Patent ID: 10395354

Abstract:
In a conductive film, a method of evaluating a pattern in the conductive film, and a display device, thin metal lines of a wiring portion is formed in a wiring pattern having quadrilateral shapes of which angles are maintained and pitches are made to be irregular. From at least one point of view, in frequencies of the moirés that are equal to or less than a frequency threshold value and are calculated for each color from two peak frequencies and two peak intensities of 2DFFT spectra of transmittance image data of rhomboid wiring patterns which are not made to be irregular and luminance image data of pixel array patterns of the respective colors at the time of lighting up for each single color, the thin metal lines has a quadrilateral wiring pattern in which angles of rhomboid shapes of rhomboid wiring patterns, each of which allows the indicator of evaluation of moirés to be equal to or less than the evaluation threshold value, are made to be irregular in a predetermined range. The indicator of evaluation is calculated from evaluation values of the moirés of the respective colors obtained by applying human visual response characteristics in accordance with an observation distance to intensities of the moirés equal to or greater than an intensity threshold value.
