Patent ID: 8724064

Claim:
A fringe field switching mode (FFS mode) liquid crystal display device (LCD) including a lower substrate, an upper substrate, and a liquid crystal layer disposed between the substrates, the lower substrate including unit pixel regions defined by gate lines and data lines formed to intersect each other and switching devices disposed on intersections of the gate and data lines, the LCD comprising: a transparent pixel electrode disposed in the pixel region; a transparent common electrode disposed on the transparent pixel electrode and spaced apart from the transparent pixel electrode with an insulating layer interposed therebetween, and having a plurality of slits formed in the pixel region, to adjust optical transmittance by applying a voltage to the liquid crystal layer, and a reflective structure formed of the same material as the gate line and disposed under the data line with an insulating layer disposed therebetween, wherein the slits are regions where the transparent common electrode is not formed, and disposed to form an angle of 5 to 10° with respect to the gate line, a rubbing direction for an initial alignment direction of the liquid crystal layer is substantially parallel to a gate direction, a drain electrode of the switching device is electrically connected to the transparent pixel electrode, and a portion of the drain electrode is formed immediately above a portion of the transparent pixel electrode, the reflective structure has a width larger than that of the data line, and boundaries between the transparent common electrode that covers the data line and the slits are disposed between one end of the data line adjacent to the boundaries and one end of the reflective structure adjacent to the boundaries.
