ABSTRACT:
A method of fabricating a color filter over a TFT array and a method of fabricating a liquid crystal display panel comprising the same are disclosed. First, a substrate having a TFT array thereon is provided. Next, a black matrix is formed over the TFT array for defining a plurality of sub-pixel regions. Next, a plurality of contact holes is formed in the black matrix. Next, an ink-jet process is performed to form a color filter pattern in each sub-pixel region respectively. Thereafter, an overcoat layer is formed over the sub-pixel regions, and then a plurality of openings is formed in the overcoat layer to expose the contact holes in the black matrix. Thereafter, pixel electrodes are formed over the overcoat layer electrically connected to the TFT array through the openings and the contact holes.
