The wide viewing angle technologies for liquid crystal displays (LCDs) are reviewed. The most promising liquid crystal modes for wide view technologies, such as in-plane switching, multidomain vertical alignment, patterned vertical alignment, and advanced-super-view are compared. By optimizing the phase-compensation films and their device configurations, the ultrawide-view LCDs with a contrast ratio higher than 100:1 at ±85° viewing cone are demonstrated.
