Compared with normal VA mode LCD, twisted-vertically aligned (TVA) mode LCD gained more and more attention due to its high transmittance as well as high contrast ratio (CR). To realize the optimized electro-optical performance and low cost, this work revealed the optical design principle of TVA mode LCD by Jones Matrix and Computer simulations. Subsequently, the TVA mode sample with high transmittance under orthogonal polarizers was obtained by optimizing the design of the pixel electrode pattern and parameters of chiral LC materials.
