A vehicular display device configured to display a guide route to a destination of a host vehicle includes a navigation device 13, a display controller 16, and a display 17. The navigation device calculates the guide route. The display controller draws an arrow having a shaft with an arrowhead at one end of the shaft, as a guide figure for guidance along the guide route as calculated, such that the arrow looks like a three-dimensional object in which a portion of the arrow with a large width has a large height and a portion of the arrow with a small width has a small height. The display displays an image drawn by the display controller in a display area provided to overlap a position of a windshield.
