  • Patent number: 8395737
    Abstract: An array substrate includes a lower substrate, a switching element and a pixel electrode. In the lower substrate, unit pixel areas are each divided into a plurality of domains. The switching element is disposed on the lower substrate and transmits a pixel signal. The pixel electrode is disposed on the unit pixel area and is electrically connected to the switching element. The pixel electrode includes a plurality of slit portions disposed thereon. A portion of the slit portions is longitudinally extended in a zigzag shape along different directions in correspondence with the domains.

  • Publication number: 20100103357
    Abstract: A liquid crystal display device includes an array substrate, an opposite substrate and a liquid crystal display layer. The array substrate includes a pixel electrode and a lower reactive mesogen layer. The pixel electrode includes a plurality of slit portions disposed on a plurality of domains in different directions. The lower reactive mesogen layer is disposed on the pixel electrode to induce an inclined direction of liquid crystal molecules. The opposite substrate includes an upper substrate. An upper reactive mesogen layer is disposed on a common electrode of the opposite substrate. The liquid crystal layer includes liquid crystal molecules arranged to have a pretilt angle between a surface of the lower reactive mesogen layer and a surface of the upper reactive mesogen layer.
