Abstract

A backlighting device including: a light guide unit formed as a substantially flat panel of a first resin material having opposing surfaces and side faces, the light guide unit having a light guide section, wherein light enters the light guide unit through at least one of the side faces and is emitted from one of the opposing surfaces; and a light source element disposed adjacent to the at least one side face of the light guide section for irradiating light onto the at least one side face of the light guide section. The light guide unit further includes a light scattering section formed of a second resin material, the light scattering section substantially perpendicularly protruding from the at least one side face of the light guide unit, and the light scattering section overlies the light source element along a direction of travel of the light exiting from the light guide section so as to scatter the light irradiated by the light source element.
