<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 irregularly shaped silica fine particles and a binder component. Irregularly shaped silica fine particles have a specific three-dimensional configuration 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 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 |
