  • Publication number: 20050128418
    Abstract: A seal pattern structure for a liquid crystal display panel is disclosed. Because an overlap portion of the seal pattern that encompasses in a closed form the outer edge of the image display part is minimized, excessive distribution of sealant at the seal pattern overlap portion may be prevented. The liquid crystal display panel including the seal pattern includes a substrate having at least one image display part; a start pattern formed from a point spaced apart from the image display part to a point adjacent to an outer edge of the image display part; a main pattern connected to the start pattern and encompassing the outer edge of the image display part; and an end pattern connected to the main pattern and formed from the outer edge of the image display part to a point spaced apart from the image display part, wherein a connection part between the start pattern and the main pattern and a connection part between the main pattern and the end pattern cross each other.
