Abstract
A projection display apparatus includes an axial fan and a louver. The axial fan includes blades which are rotated to generate an airflow in an axial direction so that air is exhausted from a housing. The louver includes inclined plate portions which are inclined with respect to the axial direction, the inclined plate portions being arranged in a direction perpendicular to the axial direction at an airflow exit side of the axial fan, the louver being divided into a first area and a second area by a straight line which passes through an axial center of the blades, the inclined plate portions being inclined in different directions between the first area and the second area such that the inclined plate portions are inclined along the direction in which the blades are rotated.
