Patent ID: 8390752

Claim:
A display device having a liquid crystal comprising: a substrate; a gate line disposed in a first direction on the substrate, and having a gate electrode; a common line on the substrate, the common line being substantially parallel to the gate line; at least a common electrode branching from the common line, wherein the common electrode and the common line are formed as a single body; an insulating layer covering the gate line, the common line, and the common electrodes; a channel pattern on the insulating layer, the channel pattern corresponding to the gate electrode; a data line disposed in a second direction and having a source electrode electrically connected with the channel pattern; a drain electrode separated from the source electrode and electrically connected with the channel pattern; and a pixel electrode electrically connected with the drain electrode and formed of an opaque metal to improve a contrast ratio, wherein the pixel electrode is formed on a passivation layer, wherein the passivation layer is formed on the data line, the channel pattern and the drain electrode, wherein the pixel electrode has a width of about 1-2 μm to improve an aperture ratio, wherein the common line is disposed across a pixel region from the gate line, wherein the common electrode and the pixel electrode are arranged in a zigzag pattern along the vertical direction of the gate line, wherein an arrangement of the liquid crystal is determined by a potential difference between the common electrode and the pixel electrode.
