At least one light-emitting member (2) is arranged on the sheet-like device. The light-emitting member (2) has a front end (5) which is positioned at or in front of the front (3) of the sheet-like device (1) and a rear opposite end (6). Said member (2) is made of a fluorescent plastic material and has a thickness which is considerably smaller than its length between said front (5) and rear (6) ends and the member (2) is adapted to absorb, between said ends (5, 6), incident light (13) and conduct this to the front end (5) for emission (26) at the front (3) of the sign unit.
