Claim 4:
5. A display comprising:
a light source;
a first 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 first light modulator incidents, the optical area having a rectangular shape in a plan view of the optical member,
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, the first axis forming 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, the second axis being perpendicular to the first axis;

an optical system configured to transmit light transmitted through the optical device;
a fixation member which is made of metal, and which is configured to fix the light modulator;
a spectral element configured to disperse the light emitted from the light source into a first colored light beam and a second colored light beam;
a second light modulator that includes a second liquid crystal panel and corresponds to the second colored light beam; and
a prism configured to combine the plurality of colored light beams modulated by the plurality of light modulators with each other, wherein
the first actuator and the second actuator are disposed at positions where the first actuator and the second actuator do not overlap the fixation member in the plan view,
the first light modulator includes a first liquid crystal panel and corresponds to the first colored light beam,
the prism combines the first colored light beam modulated by the first light modulator and the second colored light beam modulated by the second light modulator with each other, and
the fixation member fixes the prism and the first and second light modulators.
