  • Patent number: 7564525
    Abstract: A liquid crystal display device includes a first substrate, a second substrate and a liquid crystal layer interposed between the first and second substrates. At least one pixel region of the display includes a plurality of sub pixel regions in which liquid crystal molecules of the liquid crystal layer are oriented in an axially symmetrical manner. A plurality of pixel electrodes have a plurality of openings defined therein in each pixel region, the plurality of openings including a section which has been cut off from an outer shape of the pixel electrode, and the sub pixel regions are defined by sub electrode regions, in at least some of which openings defined in the pixel electrodes have their respective centers located at corners and/or sides of polygons.

  • Publication number: 20060262264
    Abstract: A liquid crystal display device includes a first substrate; a second substrate; and a liquid crystal layer interposed between the first substrate and the second substrate and having liquid crystal molecules therein. The first substrate includes a first electrode facing the liquid crystal layer. The second substrate includes a second electrode facing the liquid crystal layer. The first electrode, the second electrode, and a region of the liquid crystal layer supplied with a voltage by the first electrode and the second electrode define a pixel region which is a unit for display. The pixel region includes a plurality of sub pixel regions, in each of which the liquid crystal molecules are aligned in an axial symmetrical manner. At least one of the first electrode and the second electrode includes a plurality of openings, which are regularly arranged, in the pixel region.
