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.

Abstract: A touch sensor includes a base, first sensing electrode columns (FSECs), and second sensing electrode columns (SSECs). The base includes a sensing region (SR) including a rounded corner (RC), and a non-SR outside the SR. The FSECs extend in a direction on the base, each FSEC among the FSECs including first sensing electrodes (FSEs), each FSE among the FSEs including sub-electrodes. The SSECs are alternately disposed with the FSECs on the base, each SSEC among the SSECs including second sensing electrodes (SSEs). Sub-electrodes of one of adjacent FSEs among the FSEs are electrically connected to respective sub-electrodes of another of the adjacent FSEs. A sub-electrode closest to the RC among the sub-electrodes includes a rounded edge (RE) corresponding to the RC. A SSE closest to the RC among the SSEs includes a RE corresponding to the RC, and a protrusion part protruding toward the sub-electrode including the RE.
