Light guide plate and process for producing the same, surface light source equipment and liquid crystal display

摘要

The present invention provides a 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.Further, the present invention provides a process for producing a light guide plate, comprising the resin-coating step of 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; the step of placing an ionizing-radiation-transmissive film on the resin mass of the ionizing-radiation-curable resin; the step of spreading the film on the ionizing-radiation-curable resin while filling the mold with the ionizing-radiation-curable resin through the film by the use of press rolls; the step of curing the ionizing-radiation-curable resin by applying thereto ionizing radiation; and the step of releasing the molded product of the ionizing-radiation-curable resin from the mold.
