Disclosed is a fringe field switching mode transflective liquid crystal display capable of displaying high quality images. The transflective liquid crystal display includes a lower substrate having a counter electrode and a pixel electrode, an upper substrate aligned in opposition to the lower substrate by interposing a liquid crystal layer therebetween, an upper polarizing plate, a lower polarizing plate, a reflective plate provided at an inner portion of the lower substrate, a lower &#x3bb;/2 plate, and an upper &#x3bb;/2 plate. An inclination angle, a slit width and a slit interval of the pixel electrode of the reflective area are different from those of the pixel electrode of the transmissive area. The liquid crystal layer presents a phase delay of about 0 to &#x3bb;/4 in the reflective area and presents a phase delay of about 0 to &#x3bb;/2 in the transmissive area.

Fringe field switching mode transflective LCD having slits in the reflective area of a pixel electrode that have an inclination angle greater than slits in the transmissive area by about 10 to 40 degrees

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 (&#x394;nd) in each position of the pixel electrode.

Disclosure is a method for asymmetrically aligning polarizer and rubbing axes of a fringe field switching liquid crystal display, which removes a ghost image and a rubbing mura, caused by an electric field applied to a panel under a low gray scale and dark state, by twisting an optical axis of a polarizer plate and rubbing optical axes of upper and lower plates. The Disclosure aligns polarizer and rubbing axes of a lower plate into which polarizing light is incident in such a manner that an angle formed between the polarizer and rubbing axes is a first predetermined angle and aligns polarizer and rubbing axes of an upper plate through which the polarizing light passes via a liquid crystal in such a manner that an angle formed between the polarizer and rubbing axes is a second predetermined angle.
