Rear lighting and/or signaling device for a motor vehicle, and rear lighting and/or signaling light provided with such a device

A rear lighting and/or signaling device, notably for a motor vehicle, comprising a light source, a transmission surface and means for distributing at least a part of the light from the source on the transmission surface, the distribution means comprising

• a matrix of micromirrors that can each be driven according to at least two different inclination positions comprising a first position in which rays from the source are returned by a micromirror to the transmission surface and a second position in which the rays from the source are not returned by a micromirror to the transmission surface, wherein it comprises at least one additional light source configured such that rays from the additional source are returned by a micromirror to the transmission surface when said micromirror is in the second position and are not returned by a micromirror to the transmission surface when said micromirror is in the first position, the distribution means comprising at least one hybrid mode of operation in which the source and the additional source are simultaneously emissive and in which at least a part of the micromirrors are in the first position and at least another part of the micromirrors are in the second position.
