A spectacle lens for a display device can be fitted on the head of a user and generate an image. The spectacle lens includes a front side and a rear side, a coupling-in section and a coupling-out section spaced apart from the coupling-in section, as well as a light guiding channel which is suitable for guiding light bundles of pixels of the generated image, which are coupled into the spectacle lens via the coupling-in section of the spectacle lens, in the spectacle lens to the coupling-out section, by which they are coupled out of the spectacle lens. The light guiding channel includes a first reflecting layer, which extends from the coupling-in section to the coupling-out section and on which the light bundles are reflected for guiding to the coupling-out section. The first reflecting layer includes at least one transparent gap.
