Patent ID: 7471355

Claim:
A liquid crystal display, comprising: a light guide plate having a light-emitting plane on one end surface; a light source arranged on a side surface of the light guide plate; and a liquid crystal panel arranged opposite the light-emitting plane; wherein deflection patterns are formed on a surface opposite the light-emitting plane, the defection patterns are arranged so that two independent components on the surface opposite the light-emitting plane become random, in a certain region on the surface opposite the light-emitting plane, when an average number of the deflection patterns included in each region opposite each pixel of the liquid crystal panel is designated by μn and a standard deviation is designated by μn, their ratio satisfies the following relationship: 0 <σn/μn≦ 0.154, light from the light source introduced into the light guide plate is deflected towards the light-emitting plane by the deflection patterns so as to be emitted from the light-emitting plane, the liquid crystal panel is illuminated by the light emitted from the light-emitting plane.
