Abstract
A liquid crystal display device is provided for not reducing the aperture ratio and improving transmittance. The liquid crystal display device comprises a substrate with a pixel electrode, a substrate with a common electrode, and a liquid crystal layer therebetween, wherein liquid crystal molecules of the liquid crystal layer are vertically aligned when no voltage is applied, each pixel comprises one or more sub-pixels, and cross-shaped slits are formed on the common electrode corresponding to each sub-pixel.
