1. An electro-optical device that has a display area and a sensing area for detecting capacitance in the display area, the electro-optical device comprising:

  • a plurality of display pixels each including a plurality of sub-pixels in the display area;

    a black matrix that is provided in the vicinity of the sub-pixels;

    a pixel electrode, a common electrode and a liquid crystal layer that form the display pixel, the liquid crystal layer being interposed between the pixel electrode and the common electrode;

    a pixel circuit that drives the pixel electrode;

    a capacitance detection element that is provided between the display pixels in the sensing area such that a distance between adjacent sub-pixels is substantially equal throughout the display area; and

    a sensing circuit that outputs a sensing signal on the basis of the change in capacitance obtained by the capacitance detection element,wherein the capacitance detection element overlaps the black matrix in planar view, andwherein a distance between sub-pixels in a same display pixel is greater than a distance between the capacitance detection element and an adjacent sub-pixel.
