Abstract
A touch panel includes X electrodes which extend in a same direction, and Y electrodes which extend in a direction different from the direction of the X electrodes. The X electrodes and the Y electrodes respectively include intersection portions each formed where the X electrodes and the Y electrodes overlap each other, and electrode portions each formed between the intersection portions, wherein the electrode portions of one of the X electrodes is smaller in area than the electrode portions of one of the Y electrodes, and wherein dummy electrodes are formed close to the electrode portion of one of the X electrode or the Y electrodes.
