Abstract
The invention relates to a combined instrument (1) comprising a printed board (5), on which a light source (8) is provided that generates light for illuminating a display, and comprising a frame (31), inside of which the printed board (5) is accommodated. The display field (2) is directly mounted on the printed board (5) and a light guide (9) is provided, which is accommodated inside the frame (31) in an area adjoining the printed board (5). The light guide (9) is arranged in such a manner that light emitted by the light source (8) is fed into the light guide (9) and radiated onto the display field (2).
