A prism structure that includes: a plurality of liquid crystal devices each include a liquid crystal panel and a light emitting-side optical element, and generate an image light through modulation of any of a plurality of color lights in accordance with image information; and a cross dichroic prism that combines the image lights coming from the liquid crystal devices. In the prism structure, each of the liquid crystal devices further includes: a fixture member that is fixed to the cross dichroic prism; a retention member that keeps hold of the liquid crystal panel, and is fixed to the fixture member; and a light emitting-side optical element retention member that keeps hold of the light emitting-side optical element, and is rotation-adjustable about an illumination axis. The light emitting-side optical element retention member is rotation-adjusted about the illumination axis before fixation to the retention member.
