Patents Examined by K. Cryrus Kianni
  • Patent number: 8009240
    Abstract: Fringe field switching mode liquid crystal display (FFS LCD) devices are disclosed. A first substrate is disposed opposing a second substrate with a gap therebetween. A liquid crystal layer is interposed between the first and the second substrate. A gate line and data lines are formed on the first substrate in a matrix configuration and defining pixel areas. A counter electrode is disposed on each pixel area of the first substrate. A pixel electrode is disposed above the counter electrode with an insulating layer therebetween. The pixel electrode includes a plurality of parallel electrodes. Each electrode includes a first segment, a second segment, and a third segment, wherein the first segment has an included angle ? from the horizontal direction, the second segment has an included angle ? from the horizontal direction, and the first segment has an included angle ? from the horizontal direction.
