Method for Manufacturing compensation Optical Device for VA mode with using Nematic Crystal and compensation Optical Device for VA mode with using Nematic Crystal using thereof

摘要

The present invention relates to that, (a) alignment layer resin and the curing agent of 100% by weight of one alignment film coating solution mixing an alignment film coating composition in a solvent consisting of, including to provide a method for producing a compensating optical element for VA using a nematic liquid crystal, ⅰ) the alignment film resin is 10% to 45% by weight ⅱ) the curing agent is an alignment film coating solution by mixing from 0.1% to 10% by weight of the rotational speed to 50rpm to 5,000rpm, the rotation time is from 10 seconds to 500 seconds to after using a continuous rotary coater spin coated on the a-plate on the polarizing film, the alignment film forming step for drying and UV curing to form an alignment film; (B) a rubbing step of rubbing the alignment film formed in the above step in a horizontal direction; And (c) a continuous rotary rubbing said coating to a 5 to 50% by weight of the liquid coating solution is a nematic liquid crystal mixture in% by weight on the treated orientation layer to the rotational speed of 50rpm to 6,000rpm, the rotation time is from 10 seconds to 600 seconds, after spin-coating, using, it comprises the liquid crystal layer forming step of drying and UV curing to form a liquid crystal layer. ; VA, nematic liquid crystal, a coating, spin, spin, optical
