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 【課題】タッチ位置及び、タッチ圧力の大きさを検出するスマートフォンを提供する。【解決手段】カバー層と、カバー層の下部に位置し、液晶層及び液晶層を挟んで位置する第１ガラス層及び第２ガラス層を含むＬＣＤパネル及びＬＣＤパネルがディスプレイ機能を遂行するようにする構成を含むディスプレイモジュール２００と、ディスプレイモジュールの下部に位置する圧力電極４５０、４６０と、圧力電極の下部に位置する遮蔽用部材４７０（第１絶縁層）と、を含む。静電容量方式でタッチを感知するタッチセンサの少なくとも一部が第１ガラス層と第２ガラス層との間に位置し、タッチセンサは、複数の駆動電極と複数の受信電極とを含む。タッチセンサに駆動信号が印加され、タッチセンサから出力される感知信号からタッチ位置を検出し、圧力電極から出力される静電容量の変化量に基づいてタッチ圧力の大きさを検出する。【選択図】図５
