Zusammenfassung:	A headlamp for a motor vehicle, in particular a front headlamp, includes a first illumination device and a second illumination device for jointly generating a light distribution in front of the headlamp. The first illumination device is provided for generating a static portion of the light distribution and the second illumination device is provided for generating a dynamic portion of the light distribution. The second illumination device has a multi-aperture projection display having an illuminant and a planar digital image generator and also an array of projection lenses. The digital image generator has segments having a variable division of the respective segment into transmissive and light-non-transmissive regions. Each projection lens is assigned to a segment of the digital image generator, such that upon illumination of the array by the illuminant at least some of the segments are projected in front of the headlamp by the assigned projection lenses. The headlamp is configured in such a way that the digital image generator generates the dynamic portion of the light distribution during operation of the headlamp in the motor vehicle by varying the division into transmissive and light-non-transmissive regions for at least some of the segments.
