1. A touch sensor comprising:
a base layer comprising a sensing area and a peripheral area around the sensing area, the sensing area comprising a first area, a second area located on an outer side of the first area in a first direction and a third area located on the outer side of the first area in the second direction;
first electrode units comprising a plurality of first touch electrodes arranged on the base layer in the first direction and electrically connected to one another in the first direction, wherein the first electrode units are arranged in a second direction intersecting the first direction and spaced apart from one another in the second direction, and are located in the first area;
second electrode units comprising a plurality of second touch electrodes arranged on the base layer in the second direction and electrically connected to one another in the second direction, wherein the second electrode units are arranged in the first direction and spaced apart from one another in the first direction, and are located in the first area;
a first electrode pattern disposed adjacent the peripheral area on the base layer;
a second electrode pattern disposed on the base layer, wherein the second electrode pattern comprises a third portion disposed in the first area and electrically connected to one of the second electrode units that is adjacent thereto in the second direction;
wherein the first electrode pattern comprises a first portion located in the first area and electrically connected to one of the first electrode units that is adjacent thereto in the first direction, and a second portion extended from the first portion to the second area,
wherein a width of an entirety of the first electrode pattern in the first direction is less than a width of an entirety of each of the first touch electrodes in the first direction and is greater than half the width of the entirety of each of the first touch electrodes; and
wherein the touch sensor further comprises an edge conductive pattern disposed in the sensing area,
wherein the sensing area further comprises a corner area disposed at a corner of the sensing area, wherein the corner area is different from the first area and the second area, and
wherein the edge conductive pattern includes a rounded edge disposed along an edge of the peripheral area, the rounded edge conforming with an edge of the first electrode pattern in the second direction and an edge of the second electrode pattern in the first direction.
