Abstract
In a map display device, a viewing angle for a three-dimensional road map can be changed horizontally on a screen so that the three-dimensional road map is generated at a standard viewing angle (45°) up to a wide viewing angle (90°). At this time, the viewing angle is changed based on a reference line passing through a current position of a subject vehicle where the map display device is mounted.
