  • Publication number: 20070268437
    Abstract: In a liquid crystal display device, the device includes a first substrate, a second substrate and a liquid crystal layer interposed therebetween. The first substrate includes a pixel electrode, a thin film transistor connected to the pixel electrode, and also a hitch to connect both a lower and upper electrode of the pixel electrode. The second substrate includes a common electrode having a lower domain division part and an upper domain division part, in which each of domain division part is formed at the position corresponding to the lower and upper electrode of the pixel electrode, respectively. Through the electric field controller connected at both sides of the upper electrode of the pixel electrode, quality of display image can improve without a darkening area occurring at one part of the unit pixel.
