Abstract: A display device includes a display panel, and an electrostatic capacitive type touch panel which is formed in an overlapping manner with the display panel. A plurality of X electrodes and a plurality of Y electrodes intersecting with the X electrodes. A first signal line supplies signals to the X electrodes, a second signal line supplies signals to the Y electrodes, and the first signal line and the second signal line are formed on a flexible printed circuit board. A dummy electrode is formed adjacent to an electrode portion of each X electrode and electrode portion of each Y electrode, the dummy electrode does not overlap the X electrode and the Y electrode, and the dummy electrode does not electrically connect with the first and second signal lines.
