Abstract
The present invention relates mainly to a lighting and signalling device including at least one luminous module capable of generating a lighting beam along a longitudinal optical axis and an optical element through which the lighting beam is projected. The lighting and signalling device includes a controllable liquid-crystal screen pressed against the optical element, the controllable liquid-crystal screen being capable of adopting different diffusion states, including at least one state of projection of the lighting beam in which the controllable liquid-crystal screen is transparent and a state of emission of a signalling beam in which the controllable liquid-crystal screen is at least partially diffusing.
