ABSTRACT:
An MVA liquid crystal display which is high in brightness and has preferable characteristics is provided. Further, the MVA liquid crystal display with a preferable display quality as well as a larger margin in fabrication and a higher yield is provided. A first substrate having a first electrode, a second substrate having a second electrode corresponding to a display pixel, the liquid crystal having negative dielectric anisotropy sealed between the first and the second substrates, and a structure which is provided on each of the first and the second substrate to control an alignment of the liquid crystal are provided. The structure in the first substrate has a linear protrusion structure and provides at least two auxiliary protrusion structures opposing to each end portion facing to the second electrode extending from a protrusion structure provided and the width between the two auxiliary protrusions and the opposing second electrode is more than 6 μm respectively.
