There is provided a process for producing a light transmitting plate comprising the steps of: (1) connecting a cylinder of an injection unit with a cavity of a mold having a diagonal length of from 14 inches (355 mm) to 30 inches (760 mm), wherein (i) said mold is for making a light transmitting plate for a liquid crystal display, (ii) said mold comprises a fixed mold and a movable mold, and (iii) a cavity side of at least one mold of said fixed mold and said movable mold has a rough pattern on its surface, (2) supplying a transparent resin to said cylinder, and melting said resin, (3) filling said resin into said mold cavity from said cylinder at an injection rate of from 1 to 15 cm<3>/sec per one light transmitting plate, wherein said resin passing through an inlet of said mold has a viscosity of from 50 to 5000 Pa.sec, (4) pressing additionally said resin present in said mold cavity from a side of said cavity during or after the above-mentioned filling, and (5) cooling said resin under holding said pressure to solidify said resin, thereby obtaining a light transmitting plate having said rough pattern on its surface.
