  • 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.

  • Patent number: 9017778
    Abstract: The present invention relates to a pressure-sensitive adhesive composition, and a polarizer and a liquid crystal display (LCD) device using the pressure-sensitive adhesive composition, and more particularly, to a pressure-sensitive adhesive composition including (A) an acrylic copolymer and (B) a liquid optically-anisotropic compound having a mesogen core in its structure. The liquid optically-anisotropic compound having a mesogen core in its structure according to the present invention has superior solubility and compatibility with pressure-sensitive adhesive resin, and thus the pressure-sensitive adhesive composition including the liquid optically-anisotropic compound can relax stress caused by shrinkage of the polarizer and effectively compensate negative birefringence. Therefore, the polarizer and the LCD device using the pressure-sensitive adhesive composition can prevent light leakage originating from stress concentration in spite of long-term use.

  • Patent number: 9005477
    Abstract: A liquid crystal composition containing a polymerizable compound according to the present invention is used in a liquid crystal display element in which a liquid crystal alignment capability is provided through polymerization. The liquid crystal composition contains a polymerizable compound that polymerizes without a photopolymerization initiator or with an extremely small amount of photopolymerization initiator. Therefore, the alignment properties after the polymerization become more stable and the display characteristics do not degrade. Thus, the polymerizable compound is suitable as a practical component of the liquid crystal composition. A liquid crystal display element that uses the liquid crystal composition containing a polymerizable compound according to the present invention can be suitably used for VA and IPS liquid crystal display elements.
