  • Patent number: 8174663
    Abstract: The present invention relates to a liquid crystal display device and a method for fabricating the same, which has a structure applied thereto for preventing a liquid applied to a substrate from passing through a display portion to encroach even to a seal pattern portion causing seal breakage or gap defect. The liquid crystal display device includes first and second substrates placed opposite to each other, each having an active region at a center thereof, a seal pattern formed on an outside circumference of the active region spaced from a boundary portion of the active region, between the first substrate and the second substrate, a spread preventive wall formed on the first substrate between the boundary portion of the active region and the seal pattern, and an alignment film formed on an inner side of the spread preventive wall on the first substrate.
