1. A display device, comprising:
a cover body which forms a surface (O) facing an observer and a back face (R) facing away from the observer, wherein the cover body is formed by at least two, integrally bonded, translucent to transparent cover body components which each of the at least two cover body components form a portion of the surface (O) and a portion of the back face (R) under a formation of a common interface (G) that extends between the surface (O) and the back face (R), and wherein the at least two cover body components have different light transmittances;
at least one opaque masking layer which is applied to the surface (O) facing the observer and which, in the portion of the surface (O) formed by a less light transmissive cover body component (2a), delimits a first display area (S1) to be backlit, and wherein the portion of the surface (O) formed by a more light transmissive cover body component (2b), delimits a second display area (S2) to be backlit;
a support having a plurality of light sources arranged on a side of the cover body facing away from the observer, wherein the support is adapted to backlight the first display area (S1) or second display area (S2);
a frame made of an opaque material, integrally bonded to the cover body and adapted to secure the cover body on the support via the frame, wherein the frame extends at least in part along the common interface (G) in order to form a light barrier (4a) between the first display area (S1) and the second display area (S2).
