Patent ID: 8482704

Claim:
A method for manufacturing a liquid crystal display device, the method comprising: preparing a first substrate and a second substrate; forming gate lines and data lines crossing each other on the first substrate including first to fourth subpixel regions; forming first to fourth thin film transistors on the first to fourth subpixel regions; forming first to third reflection electrodes electrically connected to the first to third thin film transistors on reflection areas of the first to third subpixel regions; forming first to third transmission electrodes electrically connected to the first to third thin film transistors in transmission areas of the first to third subpixel regions and forming a pixel electrode electrically connected to the fourth thin film transistor in the fourth subpixel region; forming a color filter layer in regions of the second substrate that faces the first substrate and corresponds to the first to third subpixel regions; forming a common electrode on an entire surface of the second substrate; forming rib patterns long in a first direction in the fourth subpixel region on the second substrate; forming a liquid crystal layer between the first substrate and the second substrate, further comprising forming a dielectric protrusion on portions of the second substrate that correspond to the first to third subpixel regions, wherein the pixel electrode of the fourth subpixel region has slit patterns in the first direction, and wherein the first to third subpixels are selectively driven in a reflection mode and a transmission mode using a first pixel electrode slit of the first substrate and the protrusion of the second substrate, the fourth subpixel is selectively driven in a wide viewing angle mode and a narrow viewing angle mode using a second pixel electrode slit of the first substrate and a rib of the second substrate.
