Abstract
Disclosed is a fringe field switching liquid crystal display capable of improving picture quality by minimizing vertical components in a fringe field. The fringe field liquid crystal display includes: a lower substrate; a gate bus line extended on the lower substrate in a selected direction; a data bus line disposed to cross the gate bus line, thereby defining a sub pixel; a thin film transistor disposed at an intersection of the gate bus line and the data bus line; a counter electrode formed at each sub pixel and formed in shape of a rectangular plate, the counter electrode to which a common signal is continuously transmitted; and a pixel electrode electrically connected to the thin film transistor and comprising a plurality of teeth which are overlapped with the counter electrode so as to form a fringe field with the counter electrode, wherein the counter comprises a plurality of slits, and the slits are disposed between the teeth of the pixel electrode, and the counter electrode and the pixel electrode are made of a transparent conductor.
