ABSTRACT:
In a front light, an intermediate light guide protrudes from a light guide plate toward a light emitting element in the direction along a light incident face of the light guide plate. A side face of the intermediate light guide opposing the light incident face serves as an emergent face from which light from the light emitting element is emitted to the light guide plate, and an outer side face remote from the emergent face serves as a reflecting face for reflecting light propagating inside the intermediate light guide. The outer side face of the intermediate light guide is provided with a prism face having a plurality of grooves of wedge-shaped cross section, and a reflective film formed thereon. The prism face is provided distant from an end face of the intermediate light guide close to the light emitting element.
