Title:
光学フィルム
Document Type and Number:
Japanese Patent JP4336840
Kind Code:
B2
Abstract:
An optical film is provided which comprises an antireflective layer and a disperse phase of polymeric particles disposed within a continuous birefringent matrix. The film is oriented, typically by stretching, in one or more directions. The size and shape of the disperse phase particles, the volume fraction of the disperse phase, the film thickness, and the amount of orientation are chosen to attain a desired degree of diffuse reflection and total transmission of electromagnetic radiation of a desired wavelength in the resulting film.
