Abstract
A COA liquid crystal display panel includes an upper substrate, a lower substrate facing the upper substrate, and a liquid crystal layer disposed between the upper substrate and the lower substrate. The upper substrate is obtained by forming: a black matrix layer on a first base plate, a common electrode layer on the black matrix layer and exposed first base plate, and spacers on the common electrode on regions corresponding to the black matrix layer. The lower substrate is obtained by forming: a gate electrode insulation layer on a second base plate, a color barrier layer on the gate electrode insulation layer, a protective layer on the color barrier layer, a pixel electrode layer on the protective layer at a position corresponding to a projection of the color barrier layer, and a flat layer on the protective layer on a position corresponding to a recess of the color barrier layer.
