ABSTRACT:
A multi-cell gap fringe field switching mode LCD includes an upper substrate having an overcoat film and a lower substrate having a counter electrode and a pixel electrode successively formed thereon with a gate insulation film interposed between them. The overcoat film is patterned in such a manner that the cell gap at the center of the pixel electrode is different from that at the edge thereof and the overcoat film has a convex pattern formed on a part thereof corresponding to the center of the pixel electrode in a slanted profile and a concave pattern formed on a part thereof corresponding to the edge of the pixel electrode to optimize the driving voltage and phase delay value (Δnd) in each position of the pixel electrode.
