A cost‐effective wide‐viewing‐angle LCD mode, named Biased Vertical Alignment (BVA) mode, has been successfully developed by using a novel driving scheme and a new pixel design that adds a bias electrode and a bias TFT to the ordinary pixel structure. Compared to PVA and MVA modes, the BVA has a distinct advantage of lower manufacture cost due to the elimination of a lithographic process step to form either ITO‐cuts or protrusions on the color‐filter substrates. The 15″ BVA‐mode XGA prototype exhibits a high contrast ratio of 1200:1 and high cell transmittance of 4.3 %.
