The liquid crystal display device comprises a first polarizing film, a first retardation area with an Re of 70 to 330 nm and a value of Nz of not less than 0 to less than 0.5 and a slow axis perpendicular to a transmission axis of the first polarizing film; a second retardation region with an Re of not greater than 50 nm and an Rth of 10 to 140 nm; and a liquid crystal cell comprising a liquid crystal layer with a slow axis in a black state parallel to the transmission axis of the first polarizing film; and a second polarizing film in this order. | 09-11-2008 |
20080254236 | Optical Cellulose Acylate Film, Polarizing Plate and Liquid Crystal Display Device - An optical cellulose acylate film comprising a polymer component which is a cellulose acylate obtained by substituting hydroxyl groups of a cellulose by an acetyl group and an acyl group having 3 or more carbon atoms, wherein a substitution degree A of the acetyl group and a substitution degree B of the acyl group having 3 or more carbon atoms satisfy the following formulae (I) and (II): 2.0≦A+B≦3.0 (I), 0 | 10-16-2008 |
20080254237 | Polymer Film, and Optically-Compensatory Film, Polarizer and Liquid-Crystal Display Device Comprising the Same - A polymer film that has an in-plane retardation Re | 10-16-2008 |
20080297703 | Optical Cellulose Acylate Film, Polarizing Plate And Liquid Crystal Display - A cellulose acylate film is provided and includes a cellulose acylate as a polymer component. The cellulose acylate is a fatty acid ester of cellulose, obtained by substituting a hydroxyl group of cellulose with an acetyl group or an acyl group with 3 or more carbon atoms. The cellulose acylate film is a film stretched substantially by 10% or more in a casting direction or in a transversal direction to the casting direction, the film having a linear thermal expansion rate D(MD) in a casting direction (machine direction) and a linear thermal expansion rate D(TD) in a transversal direction to casting direction (i.e., perpendicular direction to casting direction) in a specified relationship. A polarizing plate utilizing such film and a liquid crystal display equipped with such polarizing plate are provided. | 12-04-2008 |
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 |
20090086125 | Process for producing cellulose acylate film, cellulose acylate film, optically- compensatory film, polarizing plate and liquid-crystal display device - A process for producing a cellulose acylate film comprising: casting a solution of a cellulose acylate having an acyl substitution degree of from 2.85 to 3.00 dissolved in at least one organic solvent onto an endless metal support; cooling the solution at 0° C. to −50° C. to effect gelation, so as to form a film; peeling the film off from the endless metal support; and drying the film. | 04-02-2009 |
20100143613 | Cellulose Acylate Film, Polarizing Plate and Liquid Crystal Display - A cellulose acylate film satisfying the following formulae: | 06-10-2010 |
