Abstract

The present invention relates to a microstructure optical film which has been devised in response to various problems and provides a microstructure optical film which enables position information on a surface to be recognised by an electronic pen, by means of forming an encoding pattern for optical deciphering on the surface of a microstructure optical film. In order to achieve this technical matter, the present invention is a microstructure optical film which enables an encoding pattern, formed on a surface, to be detected from an optical device, thus enabling position information to be determined, and the film is characterised by comprising a plurality of marks, showing position information, and a plurality of microstructures formed on the surface.
