ABSTRACT:
A multi-domain vertical alignment liquid crystal display panel comprising a first substrate, a second substrate, a liquid crystal layer and a plurality of phase-compensating protrusions is provided. The second substrate is configured above the first substrate. The liquid crystal layer is formed between first substrate and the second substrate. The phase-compensating domain regulating protrusions are formed on at least one of the first substrate and the second substrate. The phase-compensating domain regulating protrusions have a plurality of anisotropic birefringence molecules. The slow-axes of the anisotropic birefringence molecules are in a different direction from the slow-axes of the liquid crystal molecules near the phase-compensating protrusions. Therefore, the plurality of anisotropic birefringence molecules can compensate for the phase retardation here, thereby improving the light leakage in the dark state.
