We have developed a vertically aligned LCD (VA-LCD) which offers the same image quality of a CRT. This display has a super-wide viewing angle of over 70° in all directions, a fast response ( < 25 ms), and a high contrast ratio of over 300. The VA-LCD has been successfully implemented by optimizing a vertically aligned mode with a domain-divided structure and an optical compensator. We describe the optimization of a panel parameter and an optical compensator by computer simulation, and show the experimental results. We realized a 10.4-inch-diagonal VGA full-color prototype VA-LCD with super high quality.
