The present invention relates to a method for manufacturing a patterned retarder including an optical alignment layer or a first domain optically aligned in a first direction and a second domain optically aligned in a second direction. According to the invention, it is possible to improve productivity and to maximize optical alignment efficiency by reducing an optical alignment processing time using polarized pulse UV.

Optical alignment method and patterned retarder manufacturing method using polarized pulse UV

An optical alignment device using pulse UV irradiates an alignment film with pulse UV to perform optical alignment of liquid crystal. The optical alignment device using pulse UV may include a chamber, a lamp which is installed at an upper portion of the chamber and emits pulse UV light, a stage which is provided at a lower portion of the chamber and on which a substrate having an alignment film formed on a surface thereof is placed, and a polarizer which is installed detachably between the stage and the lamp.
