A compact backlighting system for illuminating a display device ( 12 ) comprises a light-emitting panel ( 1 ) having a front wall ( 2 ), an opposing rear wall ( 3 ) and edge areas ( 4 ). At least one of the edge areas ( 4 ) is capable of transmitting light. The backlighting system includes a light source ( 6 ) comprising at least one LED, and a light-mixing panel 5 for mixing the light originating from the light source ( 6 ). Light originating from the light source ( 6 ) is coupled into the light-mixing panel ( 5 ) via a light input surface ( 7 ), which light is mixed in the light-mixing panel ( 5 ) and coupled out via a light output surface ( 8 ). The light-mixing panel ( 5 ) and the light-emitting panel ( 1 ) are arranged so as to extend substantially parallel to each other. Between the light-mixing panel 5 and the light-emitting panel 1 , the backlighting system comprises a light transport chamber ( 9 ) for transporting the light from the light-mixing panel ( 5 ) to the light-emitting panel ( 1 ). Preferably, the light transport chamber ( 9 ) has elliptical, reflective inner wall ( 10 ).
