| 20080309860 | Optical Film, Optical Compensation Film, Polarizing Plate, Liquid Crystal Display Unit and Self Luminous Display Unit - An optical film which has Re(λ) and Rth(λ) fulfilling the following two formulae: | 12-18-2008 |
| 20100143613 | Cellulose Acylate Film, Polarizing Plate and Liquid Crystal Display - A cellulose acylate film satisfying the following formulae: | 06-10-2010 |
| 20100245730 | CELLULOSE ACYLATE FILM AND METHOD FOR PRODUCING SAME, RETARDATION FILM, POLARIZER AND IMAGE DISPLAY DEVICE - A method for producing a cellulose acylate film, comprising casting a polymer solution that comprises a plasticizer having a number-average molecular weight of 200-10000 and a cellulose acylate to form a web; stretching the web having a residual solvent amount of 100-300% by mass in one direction at from −30° C. to 30° C.; drying the stretched web to reduce the residual solvent amount from 6-120% by mass to less than 12% by mass while controlling the surface temperature of the web so as not to reach 200° C. or higher; and stretching the resulting film at 60-200° C. in a direction different form the stretching direction of the first stretching. | 09-30-2010 |
| 20110090439 | Retardation film, polarizing plate and liquid crystal display device - A retardation film comprising a transparent support, disposed on a surface thereof, an alignment layer and an optically anisotropic layer is disclosed. The transparent support and the optically anisotropic layer satisfy following relations: | 04-21-2011 |
| 20110311738 | Process of producing cellulose acylate film, cellulose acylate film, polarizing plate liquid crystal display device and optical compensation film - A process of producing a cellulose acylate film is disclosed. The process comprises a forming step of forming a web of a fluid, comprising a cellulose acylate, aromatic group-containing oligomer and solvent, by casting the fluid onto a support, a stretching step of stretching the web, thereby to align molecules of the aromatic group-containing oligomer along the stretching direction, and a heat-treatment step of subjecting the stretched web to a heat treatment, thereby to at least increase the alignment degree of molecules of the aromatic group-containing oligomer. | 12-22-2011 |
