Abstract

The present application discloses a touch panel including a base substrate, a first touch electrode layer on the base substrate, and a second touch electrode layer. The first touch electrode layer includes a plurality of first touch electrodes. Each of the plurality of first touch electrodes includes a plurality of first touch electrode patterns along a second direction, each of which extending substantially along a first direction. The second touch electrode layer includes a plurality of second touch electrodes along the second direction. Each of the plurality of second touch electrodes extends substantially along the first direction. The first touch electrode layer and the second touch electrode layer are insulated from each other.
