  • Patent number: 9040115
    Abstract: 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 polyarlate 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 that 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.

  • Publication number: 20120252969
    Abstract: The present invention relates to a polyarylate prepared by a method comprising a step of copolymerizing divalent phenol, divalent aromatic carboxylic acid halide and the allyl bisphenol derivative. The polyarylate according to the invention is a novel polyarylate in which various functional groups can be introduced to the main chain of the polymer as well as the terminal of a polymer, and the concentration thereof can be adjusted. These functional groups allow improvement in the adhesion force by chemically bonding with the substrate or protective layer when coated, thus the polyarylate is suitably used for a film or a coating composition.
