A display device with a touch panel includes a display panel, and a touch panel formed above the display panel. The touch panel includes X electrodes which extend in a first direction, and Y electrodes which extend in a second direction different from the first direction. 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 floating electrodes are formed close to the electrode portion of the one of the X electrodes or Y electrodes, and over a reduced portion of the X electrode.

Touch panel

Capacitive touch panel

An electrostatic capacitive coupling type touch panel including an input region having four sides, a peripheral region around the input region, terminals formed in the peripheral region along a first side of the input region, wirings formed in the peripheral region along second, third and fourth sides of the input region, and the input region having X and Y electrodes crossing. The wirings are connected between corresponding X or Y electrodes and wiring terminals plurality of terminals. A dummy wiring, which is not connected to any of the X electrodes or Y electrodes, is provided outside the wiring formed in a farthest position from the input region, and the dummy wiring extends through the peripheral region along the second, third and fourth sides of the input region, and electrically connects to at least one dummy wiring terminal.

A capacitance detection device of a capacitance system includes: a capacitance sensor electrode for detecting a capacitance; a power source for supplying charges to be charged in the capacitance sensor electrode; an electric charge storage capacitor in which an amount of charges to be charged therein changes according to the electric charges charged in the capacitance sensor electrode; and a switch for changing a reference potential of the electric charge storage capacitor. The reference potential of the electric charge storage capacitor is changed in a period of measuring the capacitance.
