A display device for a vehicle that uses a shutter means to prevent external light from entering the interior through the lens system when a shutter switch is turned off, comprising: a motor that drives the shutter means; and a sensor that detects a state of the shutter means. and off detection means for detecting that the ignition switch is turned off, and when the detection means detects that the shutter means does not block the incidence of external light, the ignition switch is turned off by the off detection means. A display device for a vehicle, characterized in that the motor is driven in response to detection of an OFF state of a shutter switch, and the shutter means is driven to a state where external light is blocked.
