We describe the novel technology of thin photo‐patterned polarizers for LCDs. The polarizer consists of small regions with different orientations of the absorption axis and/or colors. It can be placed on the interior of the LCD cell substrate. The polarizer material consists of thin (about 0.3–0.7 micrometers) lyotropic dye layers, transferred to the substrates by UV‐curing glue or by the “photo‐alignment” method. We use photo‐chemically stable dyes as the photo‐alignment layers for the lyotropic LC and as the thin photo‐patterned polarizers.
