Abstract

An illuminated display unit (10) comprising a light guide (20) in the form of a plate, one or more light sources (100) and also one or more recesses (80, 90) arranged along at least a first edge (110) of the light guide (20). The light guide (20) has a first side (60) which faces towards an observer and also a second side (30) which faces away from an observer. The light sources (100) are connected to the light guide (20) by the light sources (100) being mounted in the recess(es) (80, 90). The edges (121, 122, 123) of the light guide are coated with reflective material. The light guide (20) also comprises a matted surface (35) arranged on the second side (30) of the light guide. The display unit (10) has a reflective layer (40) arranged on the matted surface (35) of the second side (30) of the light guide. A transparent information carrier (70) may be arranged on the first side (60) of the light guide (20).
