The present invention provides a light guide plate[light guide plate?:light guide plate] for use in the surface light source equipment of a liquid crystal display or the like, wherein the light guide plate is a molded product of an ionizing-radiation-curable resin, and its maximum thickness on the light-source-fixing part side is 1.0 mm or less.
The light guide plate wherein a light-diffusive film[film?:film cutting machine] is integrally formed on the light guide plate on its light-emerging-surface side. The light guide plate wherein a film in the shape of a lens is integrally formed on the light guide plate on its light-emerging-surface side. The light guide plate according wherein a light-emerging pattern is formed on the light guide plate on its light-flux-reflecting surface side.
A process for producing a light guide plate, comprising forming a resin mass of an ionizing-radiation-curable resin at one end of the inside of a mold for shaping a light guide plate; placing an ionizing-radiation-transmissive film on the resin mass of the ionizing-radiation-curable light guide plate resin; spreading the film on the ionizing-radiation-curable resin while filling the mold with the ionizing-radiation-curable light guide plate resin through the film by the use of press rolls; curing the ionizing-radiation-curable resin by applying thereto ionizing radiation; and releasing the molded product of the ionizing-radiation-curable light guide plate resin from the mold.
