DISPLAY UNIT WITH TOUCH SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a display unit with a touch sensor suitable for use in a mobile device.SOLUTION: A display unit with a touch sensor includes: plural display pixel electrodes; a common electrode; a display function layer having an image display function; a display control circuit for performing image display control so as to exert the display function of the display function layer by applying display voltage across the display pixel electrodes and the common electrode on the basis of an image signal; a touch detection electrode provided so as to face or be aligned with the common electrode and forming a capacitance between itself and the common electrode; a circuit board having the display control circuit and the touch detection electrode formed therein; and a counter substrate disposed so as to face the circuit board. The common electrode and the display pixel electrodes are formed on the circuit board. The display function layer is provided between the display pixel electrodes on the circuit board and the counter substrate. The common electrode is disposed inside a display area of the circuit board. The touch detection electrode is formed as an electrode layer on the same layer as the common electrode in a frame area surrounding the display area on the circuit board, being separated from the common electrode.
