Abstract: In at least one embodiment, a projection display device comprises a device main body, a shutter that opens and closes an opening for ventilation, and an electricity storage section that stores power from an external power source. If an interruption detecting section detects a power supply from the external power source is stopped and a time in which the power supply is stopped is longer than a predetermined time, the interruption detecting section detects that the external power source is interrupted. If the interruption of the external power source is detected, a control section performs a control to reduce a power consumption of the device main body and a control to drive the shutter so that the shutter is closed by the power supplied from the electricity storage section.
