Patent ID: 8208098

Claim:
A liquid crystal display device comprising: a liquid crystal panel including red, green, and blue subpixels and a viewing angle control subpixel which are disposed within a second substrate adhered to a first substrate and driven by transistors connected to gate lines and data lines, wherein the viewing angle control subpixel includes a lower transparent electrode formed between a shielding electrode and an upper transparent electrode, which are formed on one surface of the first substrate, and connected to the upper transparent electrode, the lower transparent electrode and the shielding electrode being positioned with a first insulation film interposed therebetween to form a storage capacitor wherein the red, green, and blue subpixels and the viewing angle, control subpixel are arranged in a quad type to form one unit pixel, wherein the red, green, and blue subpixels operate in an FFS (Fringe Field Switching) mode, and the viewing angle control subpixel operates in an ECB (Electrically Controlled Birefringence) mode, wherein the viewing angle control subpixel comprises: the shielding electrode positioned on one surface of the first substrate, the first insulation film positioned on the shielding electrode, a lower transparent electrode positioned on the first insulation film so as to overlap with the shielding electrode, a second insulation film covering the lower transparent electrode on the first insulation film so as to expose part of the lower transparent electrode; and the upper transparent electrode positioned on the second insulation film so as to be connected to the lower transparent electrode.
