  • Patent number: 7808600
    Abstract: An LCD device for repairing to prevent gravity defects by forming a dual seal pattern in a non-display area of an LCD panel and storing surplus liquid crystal in an area between the dual seal patterns, which includes a liquid crystal panel including first and second substrates bonded to each other, and having a display area and non-display area, first and second seal patterns surrounding the display area and spaced apart from each other on the non-display area between the first and second substrates and defining a buffer space therebetween and a metal pattern formed on the first substrate under the first seal pattern, wherein the metal pattern is deformed by laser irradiation to form a path for liquid crystal to flow between the buffer space and the display area.
