<P>PROBLEM TO BE SOLVED: To provide an optical sheet having excellent abrasion resistance and hardness, and a method of manufacturing the same. <P>SOLUTION: In the optical sheet, a hard coat layer is provided on one surface of a substrate, and the hard coat layer includes a cured product of a curable resin composition for a hard coat layer, including reactive inorganic fine particles and a binder component. Fine projections have an acute angle made to a virtual plane parallel to the hard coat layer and are present on an interface on the side opposite to the substrate side of the hard coat layer. The method of manufacturing the optical sheet includes a process of applying a curable resin composition for a hard coat layer including reactive irregularly shaped silica fine particles and a binder component onto one surface of a substrate, and forming a hard coat layer and fine projections by curing the coating with or after preventing that the long axes of the reactive irregularly shaped silica fine particles are each oriented in a direction planar to a virtual plane. <P>COPYRIGHT: (C)2010,JPO&INPIT |
