Beschreibung
Zusammenfassung:	The invention discloses a light guide module including a light guide plate and a light source. The light guide plate has an active area and a light-mixed area. The active area has a centroid. The light source faces the light-mixed area, and the optical axis of the light source is not through the centroid of the active area, such that a perpendicular distance is formed between the optical axis of the light source and the centroid of the active area. The light guide module provided by the invention can uniformly distribute the light in the light guide plate to form a surface light source to emit light, and can decrease the area of the light-mixed area of the light guide plate, so that the cost of the light guide plate may be reduced, and degree of freedom for stack structure designs of products is increased.
