| 20090002613 | Retardation Compensators of Negative C-Type For Liquid Crystal Display - Disclosed is a negative C-type retardation compensator for a liquid crystal display. The negative C-type retardation compensator for the liquid crystal display includes polyarylate having a thio group or a sulfur oxide group in a polymer main chain thereof. Accordingly, the retardation compensator has an absolute value of negative retardation that is larger in a thickness direction than a retardation compensator which includes polyarylate having no thio group or sulfur oxide group in a polymer main chain thereof even though the retardation compensator having the thio group or sulfur oxide group and the retardation compensator having no thio group or sulfur oxide group are the same as each other in thickness. Thereby, the negative C-type retardation compensator for liquid crystal displays is capable of being desirably applied to the liquid crystal displays. | 01-01-2009 |
