Abstract
A projection display device includes: a leg section that supports a main body of the projection display device with respect to an installation surface on which the main body is installed; and a filter section that is disposed on a bottom of the main body and exposes a first air intake surface to the outside. In this arrangement, the first air intake surface is inclined with respect to the bottom surface of the main body in a direction that departs from the installation surface, and air flows into the filter section through a clearance between the first air intake surface and the installation surface.
