Zusammenfassung:	The system comprises a display device having a pattern of pixels associated with color filters (5B, 5G, 5R) and a backlight system for illuminating the display device, which backlight system comprises a light-emitting panel (11) and a light source (16) associated with the light-emitting panel (11). The light source (16) comprises a plurality of light-emitting diodes (LEDs) of at least three different colors, the LEDs being associated with the color filters (5B, 5G, 5R). Preferably, the spectral emission of each of the LEDs substantially matches the transmission spectrum of the color filters (5B, 5G, 5R). Preferably, the bandwidth (FWHM=full width at half maximum) of the LEDs ranges from 10
