Abstract
Cooling chambers (R, R) for accommodating therein a cooling fluid for cooling a liquid crystal panel () are formed inside a pair of frame members () constituting an optical modulator holder (). There are provided, in the pair of frame members (), inlet ports (D,D) for inletting a cooling fluid into the cooling chambers (R, R), outlet ports (E,E) for discharging the cooling fluid inside the cooling chambers (R, R) to the outside, and a buffer section (Bf) for temporally accumulating the cooling fluid flowing therein via the inlet ports (D,D) 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.
