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.
