Spectacle lens for a display device that can be fitted on the head of a user and generates an image, wherein the spectacle lens comprises a curved front side and a curved 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, wherein the spectacle lens is constructed with several shells and comprises an outer shell and an inner shell which is joined to the outer shell, wherein a channel shell, which comprises a first reflecting surface and a second reflecting surface, is arranged between the outer and inner shell (19, 20), wherein the light guiding channel comprises at least one section of the channel shell and the two reflecting surfaces (24, 25) on which the light bundles are reflected for guiding from the coupling-in section to the coupling-out section, wherein the channel shell is arranged between the outer and inner shell (19, 20) as spacer shell, with the result that the outer and inner shell (19, 20) are not in direct contact, wherein the rear side has a curvature which is chosen such that a correction of defective vision is brought about, and wherein the channel shell, the first reflecting surface and the second reflecting surface are each formed curved, respectively, characterized in that the inner shell is joined flat to the channel shell and in that the channel shell is joined flat to the outer shell, wherein that the curved channel shell is joined to the outer shell via the curved first reflecting surface and to the inner shell via the curved second reflecting surface. wherein the spectacle lens comprises a curved front side and a curved 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, wherein the spectacle lens is constructed with several shells and comprises an outer shell and an inner shell which is joined to the outer shell, wherein a channel shell, which comprises a first reflecting surface and a second reflecting surface, is arranged between the outer and inner shell (19, 20), wherein the light guiding channel comprises at least one section of the channel shell and the two reflecting surfaces (24, 25) on which the light bundles are reflected for guiding from the coupling-in section to the coupling-out section, wherein the channel shell is arranged between the outer and inner shell (19, 20) as spacer shell, with the result that the outer and inner shell (19, 20) are not in direct contact, wherein the rear side has a curvature which is chosen such that a correction of defective vision is brought about, and wherein the channel shell, the first reflecting surface and the second reflecting surface are each formed curved, respectively, characterized in that the inner shell is joined flat to the channel shell and in that the channel shell is joined flat to the outer shell, wherein that the curved channel shell is joined to the outer shell via the curved first reflecting surface and to the inner shell via the curved second reflecting surface.
