Paper Abstract

A diffusive film characterized with a directional property was developed. This new type of diffusive film is achieved with a new technology derived from holography. Directionality of diffusive film is characterized because it diffuses the light from the determinate angle strongly more than other angles. This discriminative property is consequence of the diffusive film structure that consists of different index transparent materials. Additionally, The film is a volume type diffuser, and the surfaces are almost flat so it is possible to laminated it to various part of other elements without remarkable affecting the diffusing properties of the film. Moreover, durability of this film is actually enough to consumer applications. With these remarkable properties, this diffusive film can widely applied to display systems etc.
