Abstract
A device for a motor vehicle in order to transmit information to road users for safety is provided. The device includes a light source emitting a primary beam, a scattering element, at least one liquid-crystal display arranged between the light source and the scattering element, the at least one liquid crystal display being controlled in order to selectively transmit at least one portion of the primary beam toward the scattering element to form a secondary beam with at least two different distributions of light, and an image of the at least one liquid-crystal display being formed on the scattering element.

A device for a motor vehicle, the device comprising:
- a light source emitting a primary beam;
- a scattering element;
- and
- at least one liquid-crystal display arranged between the light source and the scattering element, the at least one liquid crystal display
- being controlled in order to selectively transmit at least one portion of the primary beam toward the scattering element to form a secondary beam with at least two different distributions of light, an image of the at least one liquid-crystal display being formed on the scattering element, wherein the at least one liquid-crystal display is curved so as to allow a small angle of incidence to be obtained for each of rays of the primary beam on the at least one liquid-crystal display, the small angle of incidence being smaller than or equal to 30° degrees.
