ABSTRACT:
A liquid crystal projector device of the present invention includes a lamp unit having a lamp and a reflector, and a cooling fan for cooling the lamp unit. The reflector includes a reflecting portion having a parabolic reflecting surface, and a plurality of side walls extending from the reflecting portion to surround the lamp. A first side wall of the plurality of side walls is provided with a first air intake opening and a second air intake opening for introducing air delivered from the cooling unit toward the lamp, at both sides of a plane including a central axis of the lamp and orthogonal to the first side wall. A wind blocking wall is defined between both air intake openings. An air discharge opening is formed on a second side wall opposed to the first side wall.
