Patent ID: 8081286

Claim:
A liquid crystal display panel, comprising: a color filter array substrate including an upper substrate, a black matrix defining a cell area on the upper substrate, a color filter layer, a first column spacer, a second column spacer and an upper alignment film formed on the color filter layer, a first column spacer and the second column spacer, the first column spacer being partially inserted in a first hole defined in the color filter layer, wherein the first hole penetrates the color filter layer so that the first column spacer contacts the black matrix; and a thin film transistor (TFT) array substrate facing the color filter array substrate and including a lower substrate, a plurality of gate lines and a plurality of data lines formed on the lower substrate to define pixel regions crossing each other with a gate insulating film therebetween, a plurality of TFTs formed in crossing areas of the gate lines and the data lines, a plurality of pixel electrodes in the pixel regions connected to the TFTs through a plurality of contact holes penetrating an organic passivation film and a lower alignment film formed on the pixel electrodes and the organic passivation film, wherein the organic passivation film is flat at its whole region excluding the plurality of contact holes, wherein the first column spacer and the second column spacer has the same height, and the second column spacer is formed on the color filter over the black matrix wherein the upper alignment layer on the second column spacer is in contact with the lower alignment layer on the flat surface of the organic passivation layer, wherein the TFT array substrate further includes a storage capacitor in each pixel region and a second hole penetrating the organic passivation film to expose the storage capacitor, and wherein the first column spacer corresponds to one of the TFTs and the second column spacer is located on the second hole and corresponds to the storage capacitor.
