Abstract

A liquid crystal display mainly includes a first substrate and a second substrate; a liquid crystal having a negative dielectric constant anisotropy between the first and second substrates; and an array of first protrusions, second protrusions and third protrusions for setting the orientation of liquid crystal molecules inside pixels to a plurality of mutually different directions. The first protrusions are formed on pixel electrodes of the second substrate. Every two of the first protrusions are arranged substantially in a V-shaped pattern. The first and second protrusions are arranged alternately and in parallel to one another. The liquid crystal display of the present invention is provided with a plurality of first capacitor electrodes each in a K-shaped pattern and a plurality of second capacitor electrodes each in a V-shaped pattern wherein the first and second capacitor electrodes and the first protrusions are formed in spatially opposed relation to one another.
