Abstract
A liquid crystal display panel defines a display area and a non-display surrounding the display area. The panel includes a color filter substrate and a thin film transistor array substrate opposite to the color filter substrate. The color filter substrate includes a first substrate and a black matrix on the first substrate. The black matrix is in the display area and extending to the non-display area. A gap is defined in the black matrix and in the non-display area. The gap extends to be a circle around the display area and divides the black matrix into two independent parts. The color filter substrate includes a second substrate and a metal ring on a side of the second substrate facing the thin film transistor array substrate. The metal ring surrounds the display area and aligns with the gap.
