  • 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.
