A hybrid vehicle that uses a combination of an engine (1) and a motor generator (2) as vehicle drive sources includes a crank angle sensor (23) for detecting an engine rotational speed, and an EV lamp (44) that displays an EV state indicating that only the motor generator (2) is being used as the drive source. When in a non-EV state and the engine rotational speed is greater than a first threshold value (NE1), the EV lamp (44) is turned off. When in the EV state and the engine rotational speed is not greater than a second threshold value (NE2), the EV lamp (44) is turned on.
