Abstract: A highly reliable electrostatic-capacitive-type display device with a touch panel which allows a user to perform finger touch inputting and exhibits excellent detection sensitivity is provided. A transparent conductive film is formed above a back surface of an electrostatic-capacitive-type touch panel so as to block noises generated by a display device. A conductive member is provided to supply a voltage to a transparent conductive film formed above a back surface of the touch panel. An electrode which is formed on the electrostatic-capacitive-type touch panel is divided in accordance with a ratio between the number of X electrodes and the number of Y electrodes. A floating electrode is formed in a gap defined between the electrodes so as to adjust an area of the electrode. Due to the shrinkage of the area of the electrode, it is possible to lower a noise level to a level equal to or lower than a signal level. Accordingly, an S/N ratio is increased thus enhancing detection sensitivity.
