Zusammenfassung:	The invention relates to a light guide (10) for illuminating a light output window (120) of an illumination system (100), the illumination system, a backlighting system (100) and a display device (200). The light guide comprises a first light guide part (10A) comprising a first light guide extension (70A) extending from a first edge wall (40A) of the first light guide part (10A), and comprises a second light guide part (10B) comprising a second light guide extension (70B) extending from a second edge wall (40B) of the second light guide part (10B), the first light guide extension (70A) being configured for positioning a first light input window (80A) at a side of the second light guide part (10 ) facing a rear wall (30B) of the second light guide part (10B), the second light guide extension (70B) being configured for positioning a second light input window (80B) at a side of the first light guide part (10A) facing the rear wall (30A) of the first light guide part. An effect of the light guide according to the invention is that due to the configuration of the first light guide extension and the second light guide extension, the first light input window of the first light guide part is arranged behind the second light guide part, and the second light input window of the second light guide part is arranged behind the first light guide part.
