ABSTRACT:
Disclosed is a fringe field switching liquid crystal display, which prevents disclination lines from being created at a wedge section and improves liquid crystal polarization efficiency of a pixel electrode. The fringe field switching liquid crystal display comprises upper and lower substrates arranged while forming a space between them, a conductive black matrix formed on a lower surface of the upper substrate, a common electrode formed on an upper surface of the lower substrate, a gate insulation layer formed on an upper surface of the common electrode, and a pixel electrode formed on an upper surface of the gate insulation layer. Herein, the pixel electrode forms an electric field and includes a fringe portion having a saw-tooth shape, which forms one of 1-domain and 2-domain among the pixel electrode, the conductive black matrix, and the common electrode.
