1. A touch sensor, comprising:
a base layer having a first sensing region, a second sensing region directly connected to a first portion of the first sensing region, a third sensing region separated from the second sensing region and directly connected to a second portion of the first sensing region, and a non-sensing region surrounding the first sensing region;
a plurality of touch electrode rows provided in each of the first sensing region, the second sensing region, and the third sensing region, the plurality of touch electrode rows including a plurality of first touch electrodes connected in a first direction;
a plurality of touch electrode columns provided in each of the first sensing region, the second sensing region, and the third sensing region, the plurality of touch electrode columns including a plurality of second touch electrodes connected in a second direction different from the first direction;
a plurality of first sensing lines provided in the non-sensing region and electrically connected to the plurality of touch electrode rows;
a plurality of second sensing lines provided in the non-sensing region and electrically connected to the plurality of touch electrode columns;
a first contact electrode provided in the non-sensing region, electrically insulated from at least one of the first touch electrodes, and electrically connecting at least one of the touch electrode columns and at least one of the second sensing lines; and
a bridge line provided in the non-sensing region and overlapping and intersecting the first contact electrode, and
wherein a portion of edges of each of the second sensing region and the third sensing region includes a curved side.
