A TFT-LCD comprising: a plurality of data lines being spaced with each other; a plurality of gate lines being spaced with each other and being crossed with the gate lines; and a plurality of TFTs; wherein TFTs of the plurality of TFTs which are connected to odd data lines of the plurality of data lines, are disposed in the upside of the gate lines and the TFTs of the plurality of TFTs which are connected to the even data lines of the plurality of data lines, are disposed on the downside of the gate lines, thereby being disposed with a zig-zag form; and wherein data signals having different polarities are respectively applied to the data lines corresponding to the odd gate lines of the plurality of gate lines and to the data lines corresponding to the even gate lines of the plurality of gate lines, thereby applying the data signals having different polarities between adjacent two pixels.

Liquid crystal display

In a liquid crystal display having an upper substrate and a lower substrate opposite thereto, a liquid crystal molecules interposed therebetween, a gate bus and data bus line arranged in a first direction and the second direction respectively on the lower substrate, thus defining a space for an unit cell of the liquid crystal display, a channel layer at the intersection of the gate bus line and the data bus line, a counter electrode and a pixel electrode for operating the liquid crystal molecules disposed at unit cell and an insulating layer for isolating the gate bus line from the data bus line, the part of the counter electrode and the part of the pixel electrode by which the electric field parallel to the gate bus line are located in the space for unit cell and has sectional view of a substantial triangle shape. Accordingly, an equi-potential area in which liquid crystal molecules do not operate over the counter electrode and the pixel electrode is minimized, thus improving an aperture ratio and a transmittance of the LCD.

A method for manufacturing a fringe field switching mode liquid crystal display device which can improve productivity by reducing the number of steps in the manufacturing process. In this improved method of manufacture, the gate bus line is formed having a stacked structure of a transparent metal layer and an opaque metal layer. In the formation of the gate bus line, the counter electrode is firstly formed, and the active region is formed to cover the gate bus line. Thereafter, the counter electrode is formed by removing the opaque metal layer on the exposed surface of the counter electrode structure. By this method, the gate bus line and the counter electrode structure are formed at the same time thereby reducing the number of mask processes from six, as required by using the conventional manufacturing method, to five.
