Abstract
Disclosed herein is an very thin achromatic quarter wave film laminate for transflective LCD included in an LCD polarizer. More specifically, the very thin achromatic quarter wave film laminate for transflective LCD has a considerably reduced thickness, as compared to conventional quarter wave films in which anisotropic polymeric films are laminated.

10. A method for manufacturing a very thin achromatic quarter wave film laminate for transflective LCD comprising:
-
preparing a polymeric substrate oriented in a specific direction; coating a liquid crystal solution on the polymeric substrate; subjecting the coating to drying and UV curing to form a lower liquid crystal layer; coating a solution for an orientation film on the lower liquid crystal layer; drying the coating to form an orientation film; imparting orientation to the orientation film via polarization UV radiation or rubbing; coating a liquid crystal solution on the orientation film; and subjecting the coating to drying and UV curing to form a upper liquid crystal layer. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
