Abstract

Disclosed is a fringe field switching liquid crystal display (FFS-LCD) and a method for manufacturing the same. The FFS-LCD comprises: a lower substrate; a plurality of gate bus lines extending along a selected direction on the lower substrate; a plurality of data bus lines disposed on the lower substrate in a manner such that they are crossed with the plurality of gate bus lines, for defining a unit pixel; a gate insulating film for insulating the gate bus lines and the data bus lines from each other; a thin film transistor located at a place where the gate bus lines and the data bus lines are crossed with each other; a pixel electrode formed on the gate insulating film, brought into contact with the thin film transistor and disposed in a space of the unit pixel; a counter electrode overlapped on the pixel electrode, the counter electrode cooperating with the pixel electrode for forming a fringe field which actuates all liquid crystal molecules existing on the pixel electrode and the counter electrode; and a passivation layer intervened between the pixel electrode and the counter electrode, wherein the pixel electrode and the counter electrode are made from a transparent conductiv…
