  • Publication number: 20130027640
    Abstract: A method for manufacturing a substrate for alignment of a liquid crystal may include: forming a vertical alignment layer on a substrate; performing an alignment process on the vertical alignment layer in a first direction; forming a protective layer at a partial region of the vertical alignment layer; performing an alignment process on other regions of the vertical alignment layer in a second direction; and removing the protective layer. A liquid crystal display device manufactured using the substrate for alignment of a liquid crystal ensures wide viewing angle and alignment stability with relatively simple processes as compared with the conventional vertically aligned (VA) mode liquid crystal display device.

  • Patent number: 8310650
    Abstract: It is an object to prevent disordered orientation of liquid crystal molecules which is due to division of substrates even when a liquid crystal dripping method is used, and to provide a method for manufacturing a liquid crystal display device in which liquid crystal is not adversely affected even when a sealant not cured and liquid crystal are in contact. In a method for manufacturing a liquid crystal display device using a liquid crystal dripping method, a scribe groove is provided for at least one of a pair of substrates with a diamond cutter or the like before the pair of substrates are attached under reduced pressure. After the scribing, the pair of substrates are attached under reduced pressure, heat treatment for curing the sealant and aligning the liquid crystal molecules is performed, and the substrates are divided by applying impact using a breaking apparatus.
