Abstract
A projection display apparatus according to an embodiment of the present disclosure includes: a light source optical system including a light source section, a light conversion section that converts light emitted from the light source section to light having a wavelength band different from a wavelength band of the emitted light, and a cooling section that cools the light conversion section; and an external casing that houses the light source optical system and has an air inlet and an air outlet that form an airflow path in a linear shape. The light source section and the light conversion section are disposed on the airflow path, and the cooling section is disposed at a position shifted from the airflow path.
