Abstract: The disclosure provides a display device for head mounting, in particular a Maxwellian display device, with an enlarged eye-box. The display device includes a light source emitting light beams for forming an image, an optical system for guiding the light beams to a beam forming element. The beam forming element is configured to converge each of multiple sets of the light beams into a different point of convergence, for example on an exit pupil of the display device. Each point of convergence is a convergent viewing point for a user. The eye-box is thus enlarged.
