Claim 14:
15. The touch sensing method of claim 14, wherein delta data, which is a difference between base data and the sensing values sensed by the plurality of first-direction pattern electrodes and the sensing values sensed by the plurality of second-direction pattern electrodes, is calculated, data of each of a plurality of first-direction sub patterns close to the first diagonal point and the second diagonal point is substituted with 0 in the calculated delta data when the sum of the first touch electrode value and the second touch electrode value is greater than the predetermined threshold value, and the touch coordinates are identified based on the delta data including the data of each of the plurality of first-direction sub patterns close to the first diagonal point and the second diagonal point, which is substituted with 0.
