  • Publication number: 20060170853
    Abstract: A liquid crystal display device has no defects caused by a rubbing process. The liquid crystal display device includes a first substrate, a second substrate, a liquid crystal layer injected between the first substrate and the second substrate, and a liquid crystal alignment layer that arranges alkane chains having at least 18 carbon atoms in parallel toward the substrate. The siloxane-based liquid crystalline alignment layer produces a uniform layer that resists defects and delamination.
