Abstract
Provided is a surface film for a polarizing plate in which transparent patterns having a non-visible light reflective regularity are printed on a surface of a substrate and in which a reflection preventive layer or an antiglare layer is formed thereon or on a back side thereof, wherein an ink constituting the above transparent patterns contains a material reflecting a non-visible light. Capable of being provided is a surface film which can suitably be used for providing additional informations to an image display medium in such a manner that data are input by handwriting directly on a display device and in which the function described above is built-in from the beginning without making it necessary for the user to stick later a sheet having the above function.
