Zusammenfassung:	A compact backlight system for illuminating a display device ( 12 ) has a light-emitting panel ( 1 ) with a front wall ( 2 ) and an opposed rear wall ( 3 ) and with edge surfaces ( 4, 5 ). At least one of the edge surfaces ( 4 ) is light-transmitting. The backlight system has a light source ( 6 ) comprising a limited number of LEDs. Light from the light source ( 6 ) is coupled into the light-emitting panel ( 1 ) via the edge surface that is light-transmitting. According to the invention, the light-emitting panel ( 1 ) is wedge-shaped, and the surface area Si of the light-transmitting edge surface ( 4 ) and the surface area Sr of the opposite edge surface ( 5 ) fulfill the relation: 1
