1. A lighting device for a motor vehicle, the lighting device comprising:
at least one first module for at least one first signal light function, the at least one first module has at least one first light source and produces light with a first color in operation of the at least one first signal light function;
at least one second module for at least one second signal light function, the at least one second module has at least one second light source and produces light with a second color different from the first color in operation of the at least one second signal light function;
a shared at least partially transparent cover for the at least one first module and the at least one second module which is designed such that in operation of the lighting device, the light emitted by the respective module escapes through the cover from the lighting device; and
an LC display arranged between the at least one first module and the cover that is controlled such that in operation of the at least one first module, at least part of the light emitted from the at least one first module enters into an inlet surface of the LC display and exits an exit surface of the LC display at least partially in the direction of the cover,
wherein the LC display is at least partially switchable between an operating state and a non-operating state, wherein in the operating state, the light emitted by the at least one first module at least partially escapes through the exit surface of the LC display and in the non-operating state, the light emitted by the at least one first module does not escape through the exit surface of the LC display, and
wherein the LC display, in the non-operating state, has a color visible from the outside through the cover which corresponds to the second color and/or the color of the at least one second module visible from the outside through the cover with the at least one second light source switched off.
