摘要： Disclosed are a fringe field switching liquid crystal display (FFS-LCD) and a method for manufacturing the same. The FFS-LCD comprises upper and lower substrates opposed to each other at a predetermined distance; a liquid crystal layer intervened between the upper and lower substrates and having a plurality of liquid crystal molecules; a gate bus line extending along a predetermined direction on an inner surface of the lower substrate; a data bus line disposed on the lower substrate in a manner such that the data bus line is crossed with the gate bus line, for defining an unit pixel; a gate insulating film intervened between the gate bus line and the data bus line; a thin film transistor located at a place where the gate bus line and the data bus line are crossed with each other; a counter electrode disposed in a space of the unit pixel of the lower substrate; a common signal line brought into contact with the counter electrode for applying a common signal to the counter electrode; a pixel electrode electrically connected with the thin film transistor and formed in a manner such that the pixel electrode is overlapped with the counter electrode, the pixel electrode cooperating with the counter electrode to form a fringe field; and a passivation film intervened between the counter electrode and the pixel electrode; wherein the common signal line being formed on the gate insulating film and made of the same material as the data bus line.
