发明名称 Electro-optical device and electronic apparatus
摘要 An electro-optical device, which has a display area and a plurality of sensing areas for detecting capacitance in the display area, includes a black matrix that is provided in the vicinities of display pixels in the display area, pixel electrodes that individually form the display pixels, a common electrode, a liquid crystal layer that is interposed between the pixel electrodes and the common electrode, a plurality of pixel circuits that individually drive the pixel electrodes, a capacitance detection element that is provided in a corresponding one of the sensing areas to convert a change in thickness of the liquid crystal layer caused by external pressure into a change in capacitance, and a sensing circuit that outputs a sensing signal on the basis of the change in capacitance obtained by the capacitance detection element. The capacitance detection element overlaps the black matrix in planar view.
