Abstract:
1. A liquid crystal display device, comprising: a first substrate; a second substrate; and a liquid crystal layer interposed between the first substrate and the second substrate, wherein, the first substrate has a plurality of scanning lines, a plurality of signal lines crossing the plurality of scanning lines and a plurality of pixel electrodes respectively connected to each of the plurality of scanning lines and the plurality of signal lines through respective switching devices, the second substrate includes a counter electrode facing the plurality of pixel electrodes, each of the plurality of pixel electrodes, the counter electrode and a region of the liquid crystal layer where a voltage is applied by the pixel electrodes and the counter electrode define a pixel region which is a unit for display, the pixel region includes a plurality of sub pixel regions, in which liquid crystal molecules of the liquid crystal layer are oriented in an axially symmetrical manner, the 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 so that the openings overlap with a perimeter 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 of polygons and at least some of the openings have their respective centers located at peripheral sides of polygons and at peripheral sides of the pixel electrode distant from corners of the pixel electrode, so that at least some of the openings at the peripheral sides of the pixel electrode are spaced apart from the corners of the pixel electrode.
