Abstract: <P>PROBLEM TO BE SOLVED: To provide a means for suppressing generation of diffracted light by unevennesses, in a front light having minute unevennesses for prevention of reflection on a light emitting surface of a light guide plate.  <P>SOLUTION: In the front light equipped with a light source and the light guide plate emitting light from the light emitting surface which is situated at the reverse side against an observation side surface by conducting light from the light source, the reflection preventive patterns comprising the minute unevennesses 30 for prevention of reflection are formed on the light emitting surface. When a wavelength of visible light with the shortest wavelength among light which is emitted from the light source 24 is λmin, the refractive index of the light guide plate is n1 and the refractive index of air is n0, the period p of the minute unevennesses 30 satisfies the following equation: p <λmin/(n0 + n1), whereby the diffracted light is prevented from being emitted from the reflection preventive patterns (light emitting surface) of the light guide plate.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
