Beschreibung
Zusammenfassung:	A compact backlight system has a light-emitting panel (1) with a Front wall (2), a rear wall (3) situated opposite thereto, and furthermore, between the front and the rear wall (2, 3), a first edge surface (4) and. opposite thereto, a second edge surface (5). A first light source (6) is associated with the first edge surface (4) which is light-transmitting. According to the invention, the light-emitting panel (1) widens over a widening section (100) from the first edge surface (4) in a direction towards the second edge surface (5), and the rear wall (3) is provided over the widening section (100) with a multiplicity of steps (13, 13', ...) of which a surface (17) facing the front wall (2) is substantially parallel to the front wall (2). Preferably, the ratio of the surface area S1 of the first edge surface (4) and the surface urea S2 of the second edge surface (5) ranges from 1.5 < S2/S1 < 3.
