Patent attributes
An liquid crystal display panel includes a first substrate, a second substrate, a liquid crystal layer disposed between the first and second substrates, a patterned black matrix layer disposed on the surface of the first substrate, a patterned first color filter layer disposed on the first substrate having a protruding portion that covers a portion of the patterned black matrix layer, a plurality of first ball spacers disposed on the surface of the patterned black matrix layer, and a plurality second ball spacers disposed on the surface of the protruding portion of the patterned first color filter layer. 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.
