A touch sensor includes first touch cells disposed in a first touch sensing area, the first touch cells each including a first touch pattern and a first dummy pattern, and second touch cells disposed in a second touch sensing area, the second touch cells each including a second touch pattern and a second dummy pattern. An area of a first dummy pattern area in which the first dummy pattern is disposed is greater than an area of a second dummy pattern area in which the second dummy pattern is disposed.
