ABSTRACT:
A liquid crystal display panel and a fabricating method thereof for preventing a generation of stains caused by a cell gap difference between an active area and an outside area are disclosed. In the liquid crystal display panel, an adhesive is placed between an upper substrate and a lower substrate that are closed in such a manner as to join an upper substrate from a lower substrate. A liquid crystal layer is provided at a closed area defined by the adhesive by a dropping system. A first pattern spacer is positioned at an active area between the upper substrate and the lower substrate. A second pattern spacer is provided such that an outside area thereof enclosing said active area has a different arrangement density from the first pattern spacer and is provided at the same plane as the first pattern spacer.
