Abstract

A multi-domain vertical alignment liquid crystal display (MVA LCD) using a negative C-plate and a biaxial film is proposed to obtain an achromatic dark state. In comparison to conventional approach which uses a negative C-plate and a positive A-plate, the maximum light leakage over entire viewing cone is reduced by ${\sim} 6X$ at $\lambda =450~{\hbox{nm}}$ and ${\sim} 4X$ at $\lambda =650~{\hbox{nm}}$. The achromatic dark state is essential for improving the contrast ratio, viewing angle and color saturation of MVA LCDs.
