  • Patent number: 9045671
    Abstract: Disclosed are (A) an acrylic pressure-sensitive adhesive; and (B) an acrylic pressure-sensitive adhesive comprising an optically anisotropic compound having at least one substituent which contains an alkyl group, alkenyl group or alkynyl group at a meta-position of a mesogen. A polarizing plate and a liquid crystal display using the same are also disclosed. The optically anisotropic compound ensures excellent compatibility with the adhesive and high birefringence. Thus, main properties such as adhesion, reliability and durability in the conditions of high temperatures or high temperatures and high humidity are not worsened. Moreover light leakage is prevented by efficiently controlling the birefringence caused by shrinkage stress of the polarizing plate.

  • Patent number: 9023968
    Abstract: A method of preparing an organopolysiloxane is provided. An organopolysiloxane, which has both a linear or cross-linking structure derived from a trifunctional siloxane unit and a linear structure derived from a difunctional siloxane unit among the molecular structures and also has a sufficiently long linear structure, can be effectively prepared. Also, the organopolysiloxane can be synthesized so that it can have a sufficiently high molecular weight, and a target product showing excellent physical properties can be effectively prepared by minimizing a ratio of a functional group such as an alkoxy group or a hydroxyl group in the synthesized organopolysiloxane.

  • 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.
