Abstract:
The present invention aims at providing a manufacturing method for an optical sheet capable of manufacturing a thin optical sheet of a uniform thickness distribution with a high thickness accuracy, and high shaping/transferring performances, and an optical sheet manufactured by using the manufacturing method. A manufacturing method for an optical sheet according to the present invention includes passing a resin discharged from a die between a touch roll and a shaping roll under pressure.
