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. Further, lines are branched on a flexible printed circuit board and intersecting lines are formed on a back surface of the flexible printed circuit board, and the intersecting lines are made to orthogonally intersect with lines formed on a front surface of the flexible printed circuit board thus lowering line capacitance.

A process is disclosed for displaying an image on a display screen and recognizing a user's input by the user's finger touch on a touch screen, the process including: a first step of displaying an original image; a second step of forming a screen pad, such that a reference image, which is a reduced duplicate of the original image, is displayed on the screen pad within the display screen, such that the reference image is overlaid with the original image, in a translucent mode that renders the original image visible through the reference image, or an opaque mode where the original image is not visible.
