Display device

A display device having a capacitance touch panel for detecting the coordinates of a touched point on the display region in a capacitance coupling system, characterized in that

• said capacitance touch panel comprises a number of X electrodes, a number of Y electrodes, and a Z electrode,
• said X electrode and said Y electrodes cross with a first insulating layer in between and are respectively formed such that pad portions and fine wire portions are alternately aligned in the direction in which the electrodes extend, and the pad portions of said X electrodes and the pad portions of said Y electrodes are arranged so as to not overlap as viewed in a plane,
• said Z electrode is formed with a second insulating layer in between so as to overlap both said number of X electrodes and said number of Y electrodes as viewed in a plane,
• said Z electrode is electrically floating, and
• a pulse signal is sequentially applied to one set of said X electrodes and said Y electrodes and a change in the signal from the other set of electrodes is detected.

A display device having a capacitance touch panel for detecting the coordinates of a touched point on the display region in a capacitance coupling system, characterized in that

• said capacitance touch panel comprises a number of X electrodes, a number of Y electrodes, and a number of Z electrodes or one Z electrode,
• said X electrodes and said Y electrodes cross with a first insulating layer in between and are respectively formed so that pad portions and fine wire portions are alternately aligned in the direction in which the electrodes extend, and the pad portions of said X electrodes and the pad portions of said Y electrodes are arranged so as not to overlap as viewed in a plane,
• said Z electrodes or Z electrode are formed so as to overlap both said X electrodes and said Y electrodes with a second insulating layer in between as viewed in a plane,
• said number of Z electrodes or one Z electrode is electrically floating,
• said second insulating layer is formed of a gas so that the volume changes when pressure is applied, and
• a pulse signal is sequentially applied to one set of said X electrodes and said Y electrodes and a change in the signal from the other set of electrodes is detected.
