1. A lighting device for a vehicle, comprising:
a lighting module having at least one light source and one luminous surface illuminated by the light source, from which light emanates during operation of the lighting device,
a liquid crystal display, wherein the liquid crystal display is a smartglass display, the liquid crystal display being arranged at least partially in front of the luminous surface in such a way that, during operation of the lighting device, at least one portion of the light emerging from the luminous surface enters an entrance surface of the liquid crystal display and emerges from an exit surface of the liquid crystal display,
wherein the lighting device is configured to control the liquid crystal display, in a targeted manner and without a polarization filter, in order to allow portions of the light impinging on the entrance surface to pass through the liquid crystal display and not to allow other portions of the light impinging on the entrance surface to pass through the liquid crystal display.
