  • Patent number: 8593611
    Abstract: A LCD panel including an active device array substrate, an opposite substrate, a liquid crystal layer, a conductive sealant and restraining elements is provided. The active device array substrate includes common lines, transfer pads and a dielectric layer. The dielectric layer has openings exposing the transfer pads. The opposite substrate has a common electrode. The liquid crystal layer and the conductive sealant are disposed between the active device array substrate and the opposite substrate. The conductive sealant surrounds the liquid crystal layer. The openings are corresponding to corners of the conductive sealant. The conductive sealant fills the openings and the common electrode is electrically connected to the transfer pads through the conductive sealant. Further, the restraining elements are between the active device array substrate and the opposite substrate and are distributed around the corners of the conductive sealant such that the conductive sealant is forced to fill into the openings.
