Document Type and Number:
Japanese Patent JP7039248
Kind Code:
B2
Abstract:
[Problem] The problem addressed by the present invention lies in providing a conductive film, a touch panel and a display device which make it possible to suppress a deterioration in the quality of images observed on the display device. [Solution] In a power spectrum obtained by means of a two-dimensional Fourier transform of each of an electrode wire pattern formed from electrode wires which bend irregularly and a reference pattern formed by regular bent lines, a value obtained by dividing, at predetermined frequency widths, the cumulative value of spectral intensity of each frequency width by the frequency width is a spectral density, and a first evaluation value, which is a common logarithm of a value obtained by dividing the cumulative value of the spectral density in a defined frequency region of the electrode wire pattern by the cumulative value of the spectral density in a defined frequency region of the reference pattern, is 3.6 or less.
