Abstract
A touch sensor includes a base layer, first touch sensor columns, second touch sensor columns, and sensing lines. The base layer includes a sensing region and a non-sensing region. The first touch sensor columns extend in a first direction. The first touch sensor columns include first touch electrodes. The first touch electrodes include sub-touch electrodes in the sensing region. The second touch sensor columns include second touch electrodes in the sensing region. The second touch sensor columns are alternately arranged with the first touch sensor columns. The sensing lines are in the non-sensing region. The sensing lines include: first sensing lines electrically connected to the sub-touch electrodes, and second sensing lines electrically connected to the second touch electrodes. The sub-touch electrodes and the second touch electrodes have different widths.
