ABSTRACT:
In accordance with another embodiment of the present invention, a LCD panel includes an active matrix substrate, a patterned substrate disposed opposite to the active matrix substrate, and a liquid crystal layer interposed between the active matrix substrate and the patterned substrate. The active matrix substrate includes a transistor, a pixel electrode having a first sub-pixel electrode and a second sub-pixel electrode, a first electrode connected to the second sub-pixel electrode, and a second electrode connected to the source electrode of the transistor and the first sub-pixel electrode. The second electrode is coupled to the first electrode so as to form a capacitor. The active matrix substrate can include a protective insulating layer between the second electrode and the pixel electrode, and the protective insulating layer can include a color filter layer. The semiconductor layer of the transistor can extends such that a portion of the semiconductor layer has the same boundary as the second electrode. The patterned substrate has an aperture that divides the liquid crystal layer into a plurality of domains. The first and second electrodes are formed along a portion of the aperture of the patterned substrate.
