Claim 8:
9. A display comprising:
a light source;
a light modulator configured to modulate light emitted from the light source;
an optical device including
an optical member having an optical area on which light modulated by the light modulator incidents, the optical area having a rectangular shape in a plan view,
a first actuator configured to displace the optical member around a first axis which passes through a center of the optical area in the plan view, and the first axis forms an angle smaller than 90° with a first side of the optical area, and
a second actuator configured to displace the optical member around a second axis which passes through the center of the optical area, and the second axis is perpendicular to the first axis;

a drive circuit; configured to perform
exciting the first actuator by outputting a first drive signal to the first actuator,
exciting the second actuator by outputting a second drive signal to the second actuator, and
setting a value of the second drive signal to a value for substantially stopping exciting the second actuator in a period of the exciting the first actuator; and

an optical system configured to transmit the light transmitted through the optical device.
