Abstract
A light module for a motor vehicle headlamp comprising at least one pixelated light source, a plurality of electroluminescent emitters distributed into a plurality of pixels and capable of emitting light rays, a projection optic arranged to directly image, toward the outside of the light module, a light beam formed by said light rays emitted by said at least one light source. The light module is characterized by a mask arranged between the at least one light source and the projection optic in order to completely or partially prevent light rays originating from the light source from being reflected by regions arranged outside the plurality of electroluminescent emitters of the light source.
