Abstract
A projection display device is provided with a main body cabinet; a projection port which is formed in the main body cabinet to guide modulated light to an outside of the projection display device; an air outlet which is formed at least in one of two surfaces of the main body cabinet facing each other across the projection port; and an exhaust unit which discharges, to the outside, air that has been warmed by heat exchange with a member to be cooled which is disposed in the main body cabinet through the air outlet. In this arrangement, the exhaust unit includes an exhaust fan, and a deflection member which deflects air discharged from the exhaust fan in a direction away from the projection plane.
