Abstract

The invention relates to a light guide (1) for an imaging device for generating a virtual image from an original image having at least two different original image field regions (121, 122). The light guide (1) comprises: - a light-coupling structure (9, 25) for coupling beams originating from the original image into the light guide (1) and - a flat decoupling structure (13) for decoupling the beam coupled into the light guide (1) from the light guide (1), wherein the flat decoupling structure (13) comprises at least two partial areas (131, 132) and wherein each partial area (131, 132) is associated with another of the original image field regions (121, 122) and decouples the beam originating from the corresponding original image field region (121, 122). The partial areas (131, 132) of the decoupling structure (13) are inclined towards one another about two axes that are not parallel. The light guide (1) can be part of an imaging device which can be used, in particular, in an Head-Mounted Display.
