Abstract
An LCD device (300) includes a first substrate (30), a second substrate (40) disposed parallel to the first substrate, and a liquid crystal layer (33) having liquid crystal molecules interposed between the substrates. The first substrate includes a transparent plate (31), a color filter layer (38) formed on the transparent plate opposite to the second substrate, and a common electrode (39) formed on the color filter layer. The common electrode has a plurality of protruding portions (391) protruding toward the second substrate. The second substrate has pixel electrodes (35) opposite to the first substrate. The pixel electrodes define slits (351) therebetween. This configuration ensures to generate a symmetric electric field (E) distributing in several directions between the common and pixel electrodes so as to form several domains.
