1. 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, and electrically connected with one another, and the second sensor electrodes electrically separated from the first sensor electrodes;
third sensor electrodes electrically separated from the first sensor electrodes and the second sensor electrodes, each of the third sensor electrodes surrounded by one electrode of a first sensor electrode among the first sensor electrodes and a second sensor electrode among the second sensor electrodes; and
conductive patterns, each of the conductive patterns surrounded by other electrodes of the first sensor electrode and the second sensor electrode,
wherein values of first capacitances between the first sensor electrodes and the second sensor electrodes are detected in a first mode, and
wherein the values of the first capacitances and values of second capacitances between the second sensor electrodes and the third sensor electrodes are detected in a second mode.
