Abstract:
This conductive film has a difference of over 3 cycles/mm between a peak spatial frequency for a plurality of spectral peaks in a two dimensional Fourier spectrum for transmittance image data for a wiring pattern and a peak spatial frequency for spectral peaks up to the second term in a two dimensional Fourier spectrum for transmittance image data for a microprism array pattern for a prism sheet on the display unit side of a backlight unit, for a first moire obtained by interference between a wiring pattern for a conductive section and the microprism array pattern. As a result, this conductive film is capable of suppressing the occurrence of moire and can greatly improve visibility, even when arranged upon a display unit having a backlight unit using a prism sheet.
