Patent ID: 7973904

Claim:
A liquid crystal display panel, comprising: a first substrate having a first surface; a second substrate disposed parallel to the first substrate and opposite to the first surface of the substrate; a liquid crystal layer disposed between the first substrate and the second substrate; a patterned black matrix layer disposed on the first surface, wherein the patterned black matrix layer comprises a plurality of black-matrix patterns disposed in the boundaries of the adjacent sub-pixel regions respectively; a patterned first color filter layer disposed on the first surface and having a protruding portion that covers a portion of the patterned black matrix layer; a patterned second color filter layer disposed in portions of the sub-pixel regions and between the adjacent black-matrix patterns, wherein the patterned first color filter layer does not overlap the patterned second color filter layer; a plurality of first ball spacers disposed on the patterned black matrix layer; and a plurality of second ball spacers disposed on the protruding portion of the patterned first color filter layer, wherein the bottom surfaces of the second ball spacers and the bottom surfaces of the first ball spacers respectively are disposed on different planes in the liquid crystal display panel.
