VEHICULAR DISPLAY DEVICE

A vehicle display device, which emits display light from an opening toward a windshield and thereby allows a virtual image and a real image of a display image represented by the display light to be visually recognized, includes a display unit including a display element, transmitting light emitted by a light source, and displaying the display image, a reflection unit reflecting light representing the display image displayed on the display unit toward the windshield, and a control unit. The control unit executes light intensity control processing of controlling a light intensity of the light source in such a way that a real image display luminance setting when a real image is visually recognized and a virtual image display luminance setting when a virtual image is visually recognized have a predetermined luminance difference from each other.
