Abstract: A touch sensor includes a driving electrode which includes at least two divided areas electrically separated from each other, wherein each divided area includes first patterns connected to each other in a first direction and second patterns extending from the first pattern in a second direction, and a receiving electrode which is formed on the same plane as the driving electrode in the second direction, wherein the driving electrodes are respectively connected to separate driving channels by driving electrode wirings for each divided area, such that it is possible to sense touch positions over the entire area only by a smaller number of channels. Thereby, it is possible to significantly reduce the bezel width, and may maintain excellent touch sensitivity while significantly shortening the touch recognition time.
