Abstract
A pixel electrode ( ) and a common electrode ( ) having alignment control windows ( ) formed thereon, are formed on opposing substrates ( ). Alignment control assistance electrodes ( ) are formed between the substrate ( ) and a color filter ( ) in areas covering the alignment control windows ( ), and supplied with a voltage of a different polarity from that to be applied to the opposing pixel electrodes. With this arrangement, an electric field is formed in areas with the alignment control window formed thereon, whereby an alignment direction of the liquid crystal molecules is more strongly controlled.
