Abstract
A two-dimensionally extensive optical element having a light entry side and a light exit side. The optical element includes alternating transparent first regions and second regions having materials with different first refractive indices and second refractive indices. The first refractive index is higher than the second refractive index. First layers and second layers which are opaque or are switchable to be opaque are arranged at the light entry surfaces and light exit surfaces of the second regions. When the layers are opaque, the propagation directions of light passing through the optical element are limited compared to layers which are switched to be transparent.
