A light guiding structure adapted for a backlight module of a liquid crystal display is disclosed. The light guiding structure comprises a plurality of lighting elements and a light guide plate. Each of the lighting elements has an output surface and the light guide plate has a plurality of light incident units. Each of the light incident units has an incident surface opposite to the output surface, and a reflective surface forming an included angle with the incident surface. Light emitting from each of the lighting elements transmits into the light guide plate through the light incident surface, and then reflects along the reflective surface. The mixed reflective lights run into a central area of the light guide plate and deflects outward to a user's side.
