Abstract
A liquid crystal device includes: a first electrode; a second electrode; a liquid crystal layer; and a measurement circuit configured to supply a potential to the first electrode and the second electrode and measure a first electrode potential, wherein the measurement circuit supplies a potential to the first electrode and the second electrode so that a potential difference between the first electrode and the second electrode becomes a first potential difference during a first period, supplies a potential to the first electrode and the second electrode so that the potential difference becomes a second potential difference having a polarity different from that of the first potential difference during a second period after the first period, and stops supplying the potential to the first electrode and supplies the same potential as during the second period to the second electrode during a third period after the second period.
