The meter has a back light illuminating with a predetermined color, a display portion disposed in font of the back light and being changeable between a positive mode and a negative mode at a predetermined state, and a reverse control device determining whether an engine of a vehicle is in an initial starting step or the vehicle is in a running state. The control device reverses the display portion in response to a result of the determination. The control device changes the display portion from one of the positive and negative modes to the other at a lower speed when the control device determines that the vehicle engine is in an initial starting step than when the control device determines that the vehicle is in a running state. When the control device determines that the vehicle engine is in an initial starting step, the control device changes the display portion in one of the positive and negative modes from a neutral contrast state.
