ABSTRACT A device for the illumination of a line-shaped light switching mask which consists of a plurality of magneto-optical light modulation elements and which is arranged between polarizers, comprising a light source, a transmission optical system for transmitting an as large as possible part of the light emitted by the light source to the light switching mask, and also comprising at least one optical body which is arranged in the light path between the light source and the light switching mask in order to homogenize the light distribution. The transmission ion optical system comprises an adapter whose entrance surface corresponds to the geometry of the light source and whose exit surface corresponds to the geometry of the line shaped light switching mask there is arrange a thin light conductor plate. The line direction of the exit surface of the adapter as well as that of the light switching mask extends in the plane of the plate.
