Abstract: A flexible touch sensor device with improved durability is presented. More particularly, a flexible touch sensor device that can be bent or folded with low risk of damaging the wiring is presented. The touch sensor device includes: a plurality of first touch electrodes positioned at a first side of a first reference line extending in a first direction; a plurality of second touch electrodes positioned at a second side of the first reference line; first touch wiring connected to the first touch electrodes; and second touch wiring connected to the second touch electrodes, wherein the first touch wiring and the second touch wiring extend along a second direction that is non-parallel to the first direction without crossing the first reference line.
