Abstract
The display device with a touch panel includes: a display panel; and a touch panel formed to be overlaid on the display panel, in which: the touch panel includes X electrodes and Y electrodes which intersect the X electrodes; the X electrodes and the Y electrodes include intersection portions at which the X electrodes and the Y electrodes intersect each other, and electrode portions each formed between the intersection portions; and either the electrode portions of the X electrode or the electrode portion of the Y electrodes are smaller in area than another thereof so that a capacitance of one line of the X electrodes and a capacitance of one line of the Y electrodes are equal to each other. The display device with a touch panel has a large S/N ratio and a high detection sensitivity.
