Claim 8:
9. A touch detecting unit comprising:
first sensor electrodes arranged in a first direction and electrically connected with one another;
second sensor electrodes arranged in a second direction crossing the first direction, electrically connected with one another and electrically separated from the first sensor electrodes;
third sensor electrodes electrically separated from the first sensor electrodes and the second sensor electrodes; and
fourth sensor electrodes electrically separated from the first sensor electrodes and the second sensor electrodes,
wherein amounts of change in a first capacitances between the first sensor electrodes and the second sensor electrodes are detected in a first mode, and
wherein the amounts of change in the first capacitance, amounts of change in a second capacitance between the first sensor electrodes and the third sensor electrodes, and amounts of change in a third capacitance between the first sensor electrodes and the fourth sensor electrodes are detected in a second mode.
