Abstract

A liquid crystal display and a method of operating such liquid crystal display in which display operation is performed by changing a director of said liquid crystal molecules mainly in a plane parallel to first and second substrate forming a liquid crystal display panel. Liquid crystal molecules in the liquid crystal display panel have a negative anisotropy of permittivity. The liquid crystal display comprises: a first common electrode disposed on the side of said first substrate; an insulating layer formed on the first common electrode; at least one pixel electrodes each of which is formed on the insulating layer and has a plurality of opening portions; a second common electrode disposed on the side of the second substrate. The first common electrode comprises at least a particular portion formed in a particular area which extends from a non-opening portion to an opening portion of the pixel electrode and in which the first common electrode overlaps the non-opening portion in a cross section perpendicular to the substrates.
