The invention describes a vehicle display device equipped with a camera, in which a display comprising MiniLEDs or MicroLEDs is used as display unit. Displays with this active light-emitting design usually have a light-transmitting property due to their structural properties. This light-transmitting property can be advantageously used to take an image of the area (34) in front of the camera by means of a camera (26) arranged behind the display.
