ABSTRACT:
Cooling chambers (R1, R2) for accommodating therein a cooling fluid for cooling a liquid crystal panel (441) are formed inside a pair of frame members (4405, 4406) constituting an optical modulator holder (4402). There are provided, in the pair of frame members (4405, 4406), inlet ports (4405D,4406D) for inletting a cooling fluid into the cooling chambers (R1, R2), outlet ports (4405E,4406E) for discharging the cooling fluid inside the cooling chambers (R1, R2) to the outside, and a buffer section (Bf1) for temporally accumulating the cooling fluid flowing therein via the inlet ports (4405D,4406D) and rectifying a flow direction of the cooling fluid to a direction parallel to an optical modulation face and/or to a direction perpendicular to the optical modulation face.
