Abstract
A liquid crystal panel (441) has an optical modulator body (500), an accommodating portion (511) for accommodating the optical modulator body (500), a holding frame (510) for pressing and holding the optical modulator body (500) against the accommodating portion (511), and a frame member (512C) made of heat-conductive material and interposed between the optical modulator body (500) and a fixing plate (512), the frame member (512C) being provided on an outer periphery of a first substrate (501A) of a pair of substrates (501A, 501B) disposed on the side of the fixing plate (512), the fixing plate (512) and the frame member (512C) being integrally formed.
Claims20
An optical modulator that modulates a light beam irradiated by a light source in accordance with image information, comprising:
- an optical modulator body having a pair of transparent substrates between which an electrooptic material is sealed;
- and
- a dust-proof glass that is closely attached on an outer surface of at least one of the pair of substrates to prevent adhesion of dust on the other surface of the one of the substrate,
- the outer diameter of the dust-proof glass being smaller than the outer diameter of the one of the substrate.
