Patent ID: 8734608

Claim:
A method of manufacturing a diffuser-integrated prism sheet, comprising: passing a first resin sheet between an upper roll having prism-shaped recesses and a lower roll having a plurality of hemispherical protrusions to thus form the first resin sheet having prism-shaped protrusions on an upper surface thereof and a plurality of hemispherical recesses in a lower surface thereof, and then cooling the first resin sheet to thus cure it; applying an uncured resin to a predetermined thickness on an upper surface of a second resin sheet; passing the second resin sheet having the uncured resin over a roll having a plurality of hemispherical recesses and in contact therewith to thus form an uncured resin layer having a plurality of hemispherical protrusions, and then radiating UV light or applying heat to thus cure the uncured resin layer, thereby forming an upper diffuser layer; applying an adhesive on ridges of the prism-shaped protrusions of the first resin sheet, and then bringing the first resin sheet into close contact with the second resin sheet so that the ridges of the prism-shaped protrusions of the first resin sheet come into contact with one surface of the second resin sheet; and drying the adhesive.
