Abstract
A touch panel includes a base substrate, a plurality of touch electrode blocks disposed at interval on the base substrate, and a plurality of shadow elimination portions each provided between any two adjacent touch electrode blocks in the plurality of touch electrode blocks. The plurality of shadow elimination portions and the plurality of touch electrode blocks are disposed in insulation from each other, and a difference between a reflectivity of one of the plurality of shadow elimination portions and a reflectivity of a corresponding one of the plurality of touch electrode blocks adjacent to the one of the plurality of shadow elimination portions is within a threshold range.
