Patent ID: 6961165

Claim:
An optical modulation device retainer that retains a light modulator that modulates an incoming light flux in accordance with image information, comprising: a rectangular plate-like body having an opening section at a substantially center thereof that passes through the incoming light flux; a pair of standing pieces that protrude from a pair of parallel side edges of the rectangular plate-like body, and that extend along a direction into which an end edge of the rectangular plate-like body extends; an extension section that is provided at a tip of each of the standing pieces to extend toward the opposing standing piece; and a light modulator fixing section formed at a tip of the extension section that fixes the light modulator, a space enclosed by the rectangular plate-like body and the pair of standing pieces being inserted with one or more of optical conversion elements each including a substrate formed with an optical conversion film that converts an optical property of the incoming light flux, the optical conversion element being fixed with biased in a thickness direction of the substrate by a bias member.
