摘要： Each pixel has a transmissive area and a reflective area. A first alignment process area and a second alignment process area are placed such that an overlapping region is created in part of the reflective area. A region where the liquid crystal alignment direction shifts continuously is created in a boundary between the transmissive are a and the reflective are a without exception. A first liquid crystal alignment region is formed wider than the transmissive area, and a second liquid crystal alignment region is formed narrower than the reflective area.

摘要： The driving voltages for monochromatic images are sequentially applied to each of a plurality of pixels included in the display unit so as to cause each of the pixels to sequentially display the monochromatic images. A time-sequential arrangement of the driving voltages for the 2s (s is an integer equal to or larger than 2) monochromatic images that include the three primary colors of red, blue, and green is employed as one unit. Then, the one unit of arrangement of the driving voltages is sequentially applied periodically to each of the pixels included in the display unit so as to cause each of the pixels to sequentially display the monochromatic images arranged in accordance with the arrangement, wherein a color of the monochromatic image is any one of the three primary colors of red, blue, and green, each of the pixels included in the display unit being caused to display the monochromatic image at one point in time.
