  • Patent number: 7436473
    Abstract: A liquid crystal display is provided, which includes: a panel assembly including a first panel provided with a first electrode, a second panel facing the first panel and provided with a second electrode, and a liquid crystal layer interposed between the first panel and the second panel, the panel assembly partitioned into a display area displaying images and a peripheral area located around the display area; a polarizer disposed on a first surface of the panel assembly; a first light blocking member disposed on the first surface of the panel assembly; and a second light blocking member facing an interposing area between the polarizer and the first light blocking member.
    Type: Grant

  • Patent number: 7136139
    Abstract: In a method of filling a liquid crystal display panel with liquid crystal and a liquid crystal filling system using the method, a seal line and spacers are formed on a color filter substrate. A first volume defined by the seal line and a second volumes defined by the spacers are obtained. An amount of liquid crystal to be supplied into a region enclosed by the seal line is precisely calculated based on the first and second volumes. Shortage of the liquid crystal supplied into the LCD panel and overflow of the liquid crystal can be avoided. Accordingly, the steps for supplying the liquid crystal into the LCD panel may be reduced, and simultaneously peripheral regions of the LCD panel be prevented from being contaminated by the liquid crystal while the liquid crystal is filled into the LCD panel.

  • Patent number: 7075608
    Abstract: Disclosed are a rubbing cloth for aligning a liquid crystal, method of manufacturing the same, apparatus for manufacturing the same and method of manufacturing an LCD using the same. A rubbing pile formed on a rubbing cloth fabric fabricated by interweaving a weft and a warp having a length longer than that of the weft is aligned in a direction parallel to the weft. Accordingly, it is able to manufacture the rubbing cloth having a various size without a length of the alignment film and increase yield of the rubbing cloth.
