摘要： A projection display device projector capable of improving cooling efficiency of the power unit includes a light source lamp unit, a projection lens unit, an exhaust fan provided near the light source lamp unit for ventilating an outer case, and a ventilating path provided inside the power unit. A suction fan is provided at the inlet of the ventilating path which is connected to the cooling air intake port through a duct cover to directly conduct fresh air into the ventilating path. Because the interior of the power unit is cooled by fresh air which is cooler than the air inside the outer case, cooling efficiency is enhanced.

摘要： The invention provides a structure to attach a liquid crystal panel to a prism, which enables further enhancements in cooling capabilities. The structure includes a storing member fixed on a base and holding a holding frame, where a liquid crystal panel is held. Erected pieces to form a space to receive the holding frame are formed protruding on both left and right sides at the light incident side. Protrusions to form an air path with a cross-dichroic prism are formed on both left and right sides on the light emitting side. The liquid crystal panel is attached to the cross-dichroic prism through a holding member having an opening at a portion corresponding to the panel face of the liquid crystal panel.
