Abstract
In a projection video display system, display devices are irradiated with light emitted from a light sourcehoused in a body case, and a video image is projected to the outside of the body case. The system includes: a cooling fan for cooling the display devices; and an air passage for guiding air generated by driving the cooling fan to the display devices. Openings for making the display devices communicate with outside air are formed in positions corresponding to at least the display devices in the body case.
