Abstract
One substrate of a color liquid crystal display device includes a plurality of common electrodes, a plurality of pixel electrodes disposed between the plurality of common electrodes, color filters disposed between the common electrodes and the pixel electrodes, an orientation control layer disposed on the color filters for controlling the orientation of liquid crystal molecules of a liquid crystal layer, and black matrixes for shading boundaries of the color filters. An electric field parallel to the substrate is generated in the liquid crystal layer by applying a voltage between the common electrodes and the pixel electrodes.
