Abstract: A range shift display unit including a target range detection device that detects a selected target range and generates a range signal corresponding to the detected target range and a display processing device for driving a display portion corresponding to the target range by a driving method for a predetermined target range. Since the display portion corresponding to the target range is driven by a driving method for a predetermined target range based on the range signal, the driver can identify which range the target range is by seeing the display device.
