An optical display element (10) made up of selectively illuminatable concentric rings (14) is provided, in which the rings (14) are obtained by the light exit surface (20) of a respective optical waveguide body (18). Each optical waveguide body (18) has a light entry surface (22) which couples light in from an associated light source (24) which is adapted to be selectively activated. The light entry surface (22), as related to the common axis (12), has a larger radial extent than the light exit surface (20). Further, the optical waveguide bodies (18) have directly radially adjacent light-blocking side surfaces (30). Owing to this configuration, it is solely the optical waveguide bodies (18) which determine the geometry of the concentric rings (14). Since the optical waveguide bodies (18) can be manufactured with high precision, the intended close tolerances are obtained. In this way, radial distances between the rings (14) of only approximately 0.2 mm or less can be achieved. |
