Abstract

Vertically aligned liquid crystal displays (VA-LCDs) have now been well developed and are widely used in televisions (TV), monitors, notebooks, and mobile devices due to the many advantages that they have over other LC modes. In particular, the contrast ratio in the normal direction is very high, and by adopting a multi-domain technique, a wide viewing angle is also possible. In contrast with some other LC modes, yields are higher because of the possibility of rubbing-free mass-production, and there is the additional possibility of creating transflective displays. In this chapter, various VA-LCD modes and their respective advantages as well as the principal configuration of transflective displays are discussed.
