Abstract
A multi-domain vertical alignment liquid crystal display device includes upper and lower substrates having upper and lower alignment layers, a pixel electrode on the lower substrate, and a liquid crystal layer between the upper and lower alignment layers. The upper alignment layer is alignment-treated to define a specified alignment direction. The pixel electrode is arranged to define a desired pattern of slits or floating electrodes. The liquid crystal layer includes liquid crystal molecules having negative dielectric anisotropy (&Dgr;∈).
