A liquid crystal display (LCD) panel includes an active device array substrate, an opposite substrate, a sealant, a liquid crystal layer, a black matrix, and a plurality of rough structures. The active device array substrate has a display area and a peripheral area surrounding the display area, and the liquid crystal layer and the peripheral area are surrounded by the sealant. The black matrix is disposed between the active device array substrate and the opposite substrate and distributed corresponding to the display area and the peripheral area. The rough structures are disposed on a portion of the black matrix and distributed corresponding to the peripheral area. Surface roughness of the rough structures is greater than surface roughness of the black matrix distributed corresponding to the display area.
