Abstract: A polymeric lyotropic liquid crystal solution comprises a birefringent aromatic polymer. A linear polarizer layer is obtained by shear-coating the polymeric lyotropic liquid crystal solution on a coatable substrate, and treating the resulting coating layer with a doping-passivation solution containing iodine and multi-valent cations. A linear polarizer includes a birefringent coating layer of 1.0 micrometers or less in thickness, and contains birefringent aromatic polymer, iodine anions, and multi-valent cations. An optical article includes an optical retarder layer of 1.0 micrometers or less in thickness and a linear polarizer layer of 1.0 micrometers or less in thickness, with an intermediate layer between the linear polarizer layer and the optical retarder layer.

Abstract: An organic polymer solution may include about 0.1%-30% by weight of a specific polymer having rigid rod-like molecules. These molecules may include various cores, spacers, and sides groups to ensure their solubility, viscosity, and cross-linking ability. The rigid rod-like molecules are selected in such a way that they form self-assembling structures in the polymer solution, which makes it a lyotropic liquid crystal. The organic polymer solution, when properly deposited on a substrate and dried to remove solvents, forms a solid optical retardation layer of positive A-type substantially transparent to electromagnetic radiation in the visible spectral range.
