Abstract:
Provided are an optical device, in particular, large active reflective polarizer and a liquid crystal display (LCD) employing the same. The optical device includes: a magnetic material layer having a plurality of magnetic particles and an insulating medium to substantially prevent agglomeration between the magnetic particles; and a magnetic field generating unit applying a magnetic field to the magnetic material layer.
