A liquid crystal device includes a liquid crystal panel, a touch panel, a position signal generating device, and a display control device. The liquid crystal panel is formed so that a liquid crystal is sealed in a gap between an element substrate and an opposite substrate, which are opposed to each other, and a transmittance ratio of the liquid crystal is controlled on the basis of a voltage applied between a first electrode and a second electrode. The touch panel is arranged on a side of the opposite substrate and provided with a plurality of detection electrodes. The position signal generating device specifies one or plurality of the plurality of detection electrodes in conformity with a predetermined rule and generates a position signal that indicates a position of a pointing body on the basis of an electric potential of the specified detection electrode or on the basis of electric potentials of the specified detection electrodes. The display control device displays an image of a fixed luminance level on a display area of the liquid crystal panel, which overlaps the detection electrode or detection electrodes specified by the position signal generating device.
