ABSTRACT:
A projector includes an image projection device, an exterior chassis accommodating the substantially L-shaped image projection device, and a ventilation device configured to block leakage light and to insulate sound of the projector and to discharge air inside the exterior chassis to the outside through an air outlet formed on an end face located in a direction of projection. The image projection device includes a light source device, an optical modulation device, and a projection optical device. The ventilation device includes an axial fan with a suction port and a discharge port. An air outlet duct bends air discharged from the discharge port at an angle of substantially ninety degrees by a vertical wall substantially perpendicular to the discharging direction of air from the discharge port of the axial fan towards a side receding from the projection optical device to lead to the air outlet of the exterior chassis.
