An injection molding method for making a large and thin light guide plate, is provided. First, a first mold and a second mold are provided. The first and second molds each have a molding surface formed thereon. Second, the first mold and the second mold are incorporated together to define a chamber between the molding surfaces under a clamping force selected in a range from 4000 to 4500 kilonewton to the first and second molds. Third, inject a molding material into the chamber with an injection pressure selected in a range from 2000 to 4000 kilogram force per square centimeter and an injection velocity selected in a range from 800 to 1000 millimeter per second. Finally, the first mold and the second mold are separated to obtain the light guide plate.
