Disclosed is a liquid crystal display comprising: a first substrate and a second substrate, the first substrate being disposed opposite the second substrate and being disposed a first distance apart, each of the substrates having an inner surface and an outer surface opposite the inner surface; a liquid crystal layer sandwiched between the inner surfaces of the substrates, the liquid crystal layer including a plurality of liquid crystal molecules; a first electrode formed on the inner surface of the first substrate, the first electrode having a first width; and a second electrode formed on the inner surface of the first substrate, the second electrode having a second width, and spaced apart from the first electrode by a second distance, the first electrode and the second electrode being capable of aligning the liquid crystal molecules using an electric field produced between the first electrode and the second electrode, wherein the first distance is greater in length than the second distance, and the first and second electrodes each has a width to such a degree that the liquid crystal molecules above the first and second electrodes are substantially aligned by the electric field.

Liquid crystal display having high transmittance and high aperture ratio

Disclosed is a method of manufacturing a fringe field switching mode liquid crystal display device which can simplify process by reducing mask number. According to the present invention, a first transparent metal layer and a first metal layer are sequentially deposited on a transparent insulating substrate and patterned using a first mask. Next, a gate insulating layer, an amorphous silicon layer and a silicon nitride layer are sequentially deposited on the overall substrate and the silicon nitride layer is patterned using a second mask. The pattern portion is then patterned using a third mask so as to be exposed in the shape of a plate. Thereafter, a doped amorphous silicon layer and a second metal layer are sequentially deposited on the overall substrate and the second metal layer is patterned using the fourth mask. The doped amorphous silicon layer and the amorphous silicon layer are then etched using the source and drain as a mask. Next, a passivation layer is formed on the overall substrate and etched so as to expose a portion of the source. Thereafter, a second transparent metal layer is deposited on the passivation layer so as to fill the contact hole and patterned using a sixth mask.
