An LCD panel includes an array substrate, an opposite substrate and a liquid crystal layer. The opposite substrate is opposite to the array substrate, and the liquid crystal layer is disposed between the array substrate and the opposite substrate. The array substrate includes a substrate, an array, a sealant and a stop structure. The array disposed on the substrate is a thin-film transistor array or a color filter array. The sealant has a first end and a second end, and the first and second ends form an inlet. The stop structure is placed at least between the first end of the sealant frame and a side of the substrate.
