Abstract
A projection display apparatus according to an embodiment of the present disclosure includes: a light source unit; an image formation optical system; a projection optical system; a cooling unit; and a heat exchanger. The image formation optical system includes a spatial modulation element that modulates light emitted from the light source unit. The projection optical system projects the light from the spatial modulation element. The cooling unit includes a fan that sends cooling wind to the image formation optical system. The heat exchanger is disposed to be right opposed to the fan.
