PROBLEM TO BE SOLVED: To provide a smart phone which detects a touch position and magnitude of touch pressure.SOLUTION: A smart phone comprises: a cover layer; a display module 200 disposed on a lower part of the cover layer, comprising an LCD panel including a liquid crystal layer and a first glass layer and a second glass layer which sandwich the liquid crystal layer, and comprising a configuration so that the LCD module serves as a display function; pressure electrodes 450, 460 disposed on a lower part of the display module; and a shielding member 470 (first insulation layer) disposed on a lower part of the pressure electrodes. At least a part of a touch sensor for sensing touch by an electrostatic capacitance system is positioned between the first glass layer and second glass layer, and the touch sensor includes plural drive electrodes and plural reception electrodes. A drive signal is applied to the touch sensor, a touch position is detected, based on a sensing signal outputted from the touch sensor, and magnitude of touch pressure is detected based on a change amount of the electrostatic capacitance outputted from the pressure electrodes.SELECTED DRAWING: Figure 5 |
