Abstract
Structures, devices, systems and methods of using multi-domain vertical alignment liquid crystal displays with high transmittance, high contrast ratio and wide view angle in which at least one of the electrode substrates has circular or ring-shaped openings, such as holes or slits. Circular or ring-shaped patterns for openings and electrodes have not been used in the construction of a liquid crystal display. The new multi-domain vertical alignment (MDVA) liquid crystal display is particularly suitable for liquid crystal display television and computer monitor applications.
Claims27
A multi-domain vertical alignment liquid crystal display with high transmittance, high contrast ratio and wide view angle comprising:
- a first substrate including a common electrode separated by a space from a second substrate including a pixel electrode positioned opposite the first substrate;

- the first substrate and the second substrate consisting of a pixel unit;
- a common electrode and a plurality of pixel electrodes controlled by a storage electrode;
- and
- at least one of the first substrate and the second substrate with a circular opening area without electrodes.
