20090262289TRANSFLECTIVE LIQUID CRYSTAL DISPLAY DEVICE AND COLOR LIQUID CRYSTAL DISPLAY DEVICE - A vertical alignment liquid crystal layer is sealed between a first substrate having a first electrode and a second substrate having a second electrode, each pixel region has a reflective region and a transmissive region, and a gap adjusting section is provided on one of sides of the first substrate and the second substrate which sets a thickness (gap) d of the liquid crystal layer which controls a phase difference of incident light to the liquid crystal layer so that a gap dr in the reflective region is smaller than a gap dt in the transmissive region. An alignment controller which divides alignment of the liquid crystal within a pixel region is provided in the pixel region on at least one of the sides of the first substrate and the second substrate. It is also possible to optimize by changing the gap in red, green, and blue.10-22-2009
20100315581LIQUID CRYSTAL DISPLAY DEVICE - An orientation controller which divides a pixel into a plurality of different priority alignment regions and an additional orientation controller are provided in a pixel. The additional orientation controller is provided at least at an end of a pixel of a long-side alignment region formed along the long side of the pixel among the divided alignment regions, for example, around a center position of the long side of the pixel. The additional orientation controller can be realized, for example, by forming a cutout pattern in a side of a first electrode (pixel electrode) forming a part of the pixel. Because the alignment direction is also controlled by the additional orientation controller, the alignment of liquid crystal in this region is stabilized.12-16-2010
