According to a front light comprising an optical waveguide 25 and a light
source 24 arranged on the side of the optical waveguide 25, the optical
waveguide 25 comprises a light input surface and light emission surface
28, and a plurality of deflection patterns 26 are formed on the surface
opposed to the light emission surface 28. Light from the light source 24
is input from the light input surface of the optical waveguide 25 and
propagated in the optical waveguide 25. The light totally reflected by
the deflection patterns 26 among the light propagated in the optical
waveguide 25 is emitted from the light emission surface 28 in the
direction oblique to the normal direction of the light emission surface
28. The light is emitted from the light emission surface 28 so as to be
aligned in one direction regardless of its position.
