Touch sensor including rounded corner and sensing electrode including rounded edge corresponding to rounded corner, and display device including the same

A touch sensor comprising:

• a base comprising:
• a sensing region comprising a rounded border;
• and
• a non-sensing region outside the sensing region;
• first sensing electrode columns extending in a first direction on the base, each comprising first sensing electrodes, wherein a first sensing electrode among the first sensing electrodes comprises sub-electrodes;
• second sensing electrode columns alternately disposed with the first sensing electrode columns on the base, wherein a second sensing electrode column among the second sensing electrode columns comprises second sensing electrodes;
• first sensing lines connected to the sub-electrodes, respectively;
• and
• second sensing lines connected to the second sensing electrodes, respectively,
• wherein a sub-electrode closest to the rounded border among the sub-electrodes comprises a rounded edge corresponding to the rounded border,
• wherein a second sensing electrode closest to the rounded border among the second sensing electrodes comprises a rounded edge corresponding to the rounded corner,
• wherein the sub-electrode closest to the rounded border and the second sensing electrode closest to the rounded border are adjacent each other in a row direction,
• wherein a second sensing line of the second sensing lines is connected to a first one of the second sensing electrodes included in one of the second sensing electrode columns and a second one of the second sensing electrodes included in another one of the second sensing electrode columns, and
• wherein sub-electrodes of one of adjacent first sensing electrodes among the first sensing electrodes are separated from one another and electrically connected to respective sub-electrodes of another of the adjacent first sensing electrodes through the respective first sensing lines.
