Abstract: A polarizer for use with a display device having a viewing area and a non-viewing area includes a patterned hydrophobic layer, a patterned lyotropic liquid crystal (LC) polarizer layer, a lyotropic LC polarizer alignment layer, a reactive mesogen (RM) quarter wave plate (QWP) layer, an RM QWP alignment layer, a substrate, and an adhesive. The patterned hydrophobic layer surrounds the patterned lyotropic LC polarizer layer. The patterned hydrophobic layer is wholly contained within the non-viewing area of the display device. The substrate is adjacent to the RM QWP alignment layer, and the adhesive is disposed between the substrate and the display device.
