1. A touch sensor comprising:
a base layer including a sensing area;
sensor electrodes disposed in the sensing area and including sensor patterns, the sensor patterns including first sensor patterns electrically connected along a first direction through first bridge patterns connecting the first sensor patterns, and second sensor patterns electrically connected along a second direction through second bridge patterns connecting the second sensor patterns, wherein the first sensor patterns and the second sensor patterns include non-corner unit patterns each having a first size and a corner unit pattern disposed at a corner of the sensing area and having a second size different from the non-corner unit patterns; and
dummy electrodes disposed between the first sensor patterns and the second sensor patterns,
wherein a center of the first bridge pattern included in the corner unit pattern of the first sensor patterns is not disposed on a straight line connecting centers of the first bridge patterns in the non-corner unit patterns of the first sensor patterns,
wherein centers of the second bridge patterns in the corner unit pattern and in the non-corner unit patterns of the second sensor patterns are disposed on a straight line extending along the second direction,
wherein a dummy electrode in the corner unit pattern is connected to a dummy electrode in a non-corner unit pattern disposed adjacent to the corner unit pattern,
wherein a first sensor pattern disposed at a boundary between the corner unit pattern and the non-corner unit pattern includes a first sub-sensor pattern disposed in the corner unit pattern and a second sub-sensor pattern disposed in the non-corner unit pattern, and
wherein the first sub-sensor pattern has a first length along the boundary between the corner unit pattern and the non-corner unit pattern shorter than a second length of the second sub-sensor pattern along the boundary between the corner unit pattern and the non-corner unit pattern.
