PROBLEM TO BE SOLVED: To realize a projection display device provided with a cooling mechanism capable of efficiently cooling respective parts inside a device. SOLUTION: A power source unit 7 and an optical unit 9 are housed inside a housing case. An air intake port for cooling and an air discharging port 43 are provided on the housing case. Besides, a suction fan 15 for taking air from the air intake port for cooling and an exhausting fan 16 discharging the air inside the device outside through the port 43 are provided inside the housing case. The air taken inside by the fan 15 is divided into a flow path passing through the unit 9 directly to the fan 16, a flow path through a light source lamp unit 8 to the fan 16, and a flow path through the unit 7 to the fan 16, so that the inside of the device can be sufficiently cooled. |
