A wide-viewing angle twisted-vertical alignment (TVA) liquid crystal display without appearance of disclination lines inside the display area of each pixel has been developed. With simple surrounding protrusion geometry, the liquid crystal molecules present axially symmetric orientation in each pixel when the voltage is applied and thus exhibit wide-viewing angle characteristics. The electro-optic properties of the TVA cell are simulated by the three-dimensional finite element method, and agree well with the experimental results. (C) 2010 Elsevier B.V. All rights reserved.
