Claim:
1. A liquid crystal display panel structure, comprising a color filter (CF) substrate, a thin film transistor (TFT) substrate oppositely positioned to the CF substrate, a liquid crystal layer filled between the CF substrate and the TFT substrate, sealant coated between the CF substrate and the TFT substrate and a black matrix arranged between the CF substrate and the TFT substrate, wherein the black matrix is positioned at a periphery of an active area on the CF substrate and has a height that is smaller than a distance between the CF substrate and the TFT substrate, and the black matrix comprises a plurality of trenches, and each of the trenches penetrates the black matrix to form a hollow construction, and the sealant is positioned on the black matrix and fills in the trenches for assembling and attaching the CF substrate and the TFT substrate; wherein the black matrix comprises a plurality of blocks distributed along the periphery of the active area, the plurality of blocks being spaced from each other and alternating with the trenches, the plurality of blocks of the black matrix having a width measured in a direction substantially perpendicular to the periphery of the active area and parallel to the CF substrate, the width being substantially identical to a width of the sealant measured in the direction.
