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

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

• a transparent substrate that has a three-dimensional shape;
• and
• two wiring portions that have three-dimensional shapes and are arranged on both sides of the transparent substrate or arranged on a single side,
• wherein at least one wiring portion of the two wiring portions has a mesh-shaped wiring pattern in which a plurality of opening portions formed of a plurality of thin metal lines are arranged,
• wherein in the display unit, pixels, which include a plurality of sub-pixels emitting light with a plurality of colors that are at least three colors different from each other, are arranged in pixel array patterns,
• wherein the conductive film is provided on the display unit such that the wiring patterns of the two wiring portions overlap with the pixel array patterns of the display unit,
• wherein a projected wiring pattern, which is obtained when the wiring patterns of the two wiring portions having three-dimensional shapes are projected onto a plane perpendicular to a point of view, is a combined wiring pattern including an irregular wiring pattern which has mesh shapes and has irregularity such that at least shapes of the opening portions thereof are two or more types of different opening shapes and polygonal shapes having two or more types of different numbers of vertices of the opening shapes,
• wherein an indicator of evaluation of noises, which is caused by interference between the combined wiring pattern and projected pixel array patterns obtained when the pixel array patterns are projected onto the same plane, is equal to or less than an evaluation threshold value, and
• wherein from the point of view, in frequencies and intensities of the noises of respective colors of a plurality of colors calculated from a first peak frequency and a first peak intensity of a plurality of first spectrum peaks of two-dimensional Fourier spectra of transmittance image data of the combined wiring pattern and a second peak frequency and a second peak intensity of a plurality of second spectrum peaks of two-dimensional Fourier spectra of luminance image data of the projected pixel array patterns of the respective colors when light beams with the plurality of colors are respectively emitted, the indicator of evaluation of noises is calculated from evaluation values of the noises of the respective colors obtained by applying human visual response characteristics in accordance with an observation distance to intensities of the noises equal to or greater than a first intensity threshold value among intensities of the noises at frequencies of the noises equal to or less than a frequency threshold value defined on the basis of a display resolution of the display unit.
