<p>The optical device comprises first (1) and second polarizers that are capable of moving between a first state in which polarization directions of the polarizers are parallel and a second state in which polarization directions of the polarizers are perpendicular. The polarizers: comprise an antireflective sub-micrometer structure (18); are disposed on a substrate (12) having a refractive index of less than 1.77; and are made of a polymer sheet, which is directly attached to the substrate by a rolling operation. The substrate comprises a sub-micrometer structure provided on its free face.
