ABSTRACT:
An apparatus for manufacturing a lens sheet comprises an application device, a substrate supply device, a pressing device and an irradiation device. The application device applies ionizing radiation curing type resin in the form of liquid on the upper surface of a forming die for a lens sheet to form an uncured resin body on the upper surface of the forming die. The substrate supply device places a substrate on the uncured resin body. The pressing device presses the substrate against the uncured resin body to flatten the uncured resin body, so as to form a uncured resin layer, while spreading the uncured resin body to an outside periphery of the forming die. The irradiation device irradiates ionizing radiation on the uncured resin layer through the substrate to cure the uncured resin layer.
