Abstract: A patterned linear polarizer layer is obtained by shear coating a polymeric lyotropic liquid crystal solution on a coatable substrate, drying and treating the resulting polymer layer with a doping-passivation solution containing the dopant and multi-valent cations, where the patterned structure is obtained using various methods like restricting the doping process to certain areas of the polymer layer or discoloring the doping agent in certain areas of the linear polarizer or by selective removal of parts of the linear polarizer layer and others. The thickness of the dry linear polarizer coating layer is 2.0 micrometer or less.
