A map display device and a map display method, in which a building in a map is formed as a pseudo three-dimensional figure and arithmetic processing to display the figure as a bird's-eye view is simplified. The map display device 20 for displaying map data, formed from vector data, on a display means has a plane figure-for-bird's-eye-view creation means 218, a shift amount storage means 219, a building position determination means 220, and a figure data copying means 221. The plane-figure-for-bird's-eye-view creation means 218 creates, from the map data formed from vector data, a plane figure for creating a bird's-eye view. The figure data copying means 221 copies and draws the plane figure to display a bird's-eye view. This is performed based on the positions of buildings determined by the building determination means 220 and on the shift amounts stored in the shift amount storage means 219, and in this process, the plane figures are shifted upward on a display screen according to the shift amounts, and the copying and drawing are made one by one from a building positioned on the far side in the bird's-eye view.
