TOUCH PANEL SENSOR, TOUCH PANEL DEVICE, AND DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a touch panel sensor that has a detection electrode formed in a mesh pattern that makes both moire and unevenness in light and shade inconspicuous.SOLUTION: A touch panel sensor 25 includes a detection electrode 45 that forms a mesh pattern 50 defining a plurality of opening areas 51. A Fourier transformation power spectrum image specified from scan data of a mesh pattern formed by using a plane scanner satisfies a predetermined condition.
