  • 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: 8488086
    Abstract: A method for producing a light reflecting structure in a transflective or reflective liquid crystal display uses one or two masks for masking a photoresist layer in a back-side exposing process. The pattern on the masks is designed to produce rod-like structures or crevices and holes on exposed and developed photoresist layer. After the exposed photoresist is developed, a heat treatment process or a UV curing process is used to soften the photoresist layer so that the reshaped surface is more or less contiguous but uneven. A reflective coating is then deposited on the uneven surface. One or more intermediate layers can be made between the masks, between the lower mask and the substrate, and between the upper masks and the photoresist layers. The masks and the intermediate layers can be made in conjunction with the fabrication of the liquid crystal display panel.

  • Publication number: 20080199638
    Abstract: A method for producing a light reflecting structure in a transflective or reflective liquid crystal display uses one or two masks for masking a photoresist layer in a back-side exposing process. The pattern on the masks is designed to produce rod-like structures or crevices and holes on exposed and developed photoresist layer. After the exposed photoresist is developed, a heat treatment process or a UV curing process is used to soften the photoresist layer so that the reshaped surface is more or less contiguous but uneven. A reflective coating is then deposited on the uneven surface. One or more intermediate layers can be made between the masks, between the lower mask and the substrate, and between the upper masks and the photoresist layers. The masks and the intermediate layers can be made in conjunction with the fabrication of the liquid crystal display panel.
