1. A liquid crystal apparatus comprising:
a first electrode;
a liquid crystal layer;
a second electrode facing the first electrode via the liquid crystal layer; and
a measurement circuit configured to supply a potential to each of the first electrode and the second electrode and measure a potential of the first electrode, wherein
the measurement circuit
supplies a first potential to the first electrode, and supplies a second potential higher than the first potential to the second electrode in a first period,
supplies the first potential to the first electrode and supplies a third potential higher than the first potential and lower than the second potential to the second electrode in a second period after the first period,
supplies a fourth potential higher than the third potential and lower than the second potential to the first electrode and supplies the third potential to the second electrode in a third period after the second period, and
stops supply of the potential to the first electrode and supplies the third potential to the second electrode in a fourth period after the third period.
