Very thin achromatic quarter wave film laminate for transflective LCD and method for producing the same |
摘要 |
Disclosed herein is a method for manufacturing a very thin achromatic quarter wave film laminate for transflective LCD including steps of (1) preparing a polymeric substrate oriented in a specific direction; (2) coating a liquid crystal solution on the polymeric substrate; (3) subjecting the coating to drying and UV curing to form a lower liquid crystal layer; (4) coating a solution for an orientation film on the lower liquid crystal layer; (5) drying the coating to form an orientation film; (6) imparting orientation to the orientation film via polarization UV radiation or rubbing; (7) coating a liquid crystal solution on the orientation film; and (8) subjecting the coating to drying and UV curing to form a upper liquid crystal layer. The very thin achromatic quarter wave film laminate for transflective LCD manufactured by this method has a considerably reduced thickness, as compared to conventional quarter wave films in which anisotropic polymeric films are laminated.
