<p>An optical modulator holder ( 4402 ) has an optical modulator holding unit ( 4405 ) having a substantially rectangular U-shaped cross-section and made of heat-conductive material, a plate-like member ( 4406 ) made of heat-conductive material, and an optical modulator cooling unit ( 4407 ) constituted by a hollow member which is capable of enclosing cooling fluid inside and is made of heat-conductive material. Of the optical modulator holding unit ( 4405 ) and the plate-like member ( 4406 ), peripheries of openings ( 4405 A 1, 4406 A) each contact heat-transferably a liquid crystal panel ( 441 ). The liquid crystal panel ( 441 ) is held inside the rectangular U-shape of the optical modulator holding unit ( 4405 ). The optical modulator cooling unit ( 4407 ) is formed like a ring whose inner side surface heat-transferably contacts the liquid crystal panel ( 441 ), and has an inlet port ( 4407 D) and outlet port ( 4407 E).</p> |
