Optical film and method for manufacturing the same and liquid crystal display device using the same

摘要

An optical film is provided. The optical film includes a substrate, a first transmission medium, second transmission medium, and a reflective polarizing film. The first transmission medium is disposed at the front surface of the substrate and includes a plurality of embossed microlenses. The second transmission medium is disposed at the rear surface of the substrate and comprises a plurality of V-shaped prisms. The reflective polarizing film is disposed at the front surface of the first transmission medium. The substrate, the first transmission medium, and the second transmission medium are bounded to each other to form a unitary sheet.
