Abstract

A vertical alignment type liquid crystal display, having a specific resistance within a range of from 1*1010 [Omega]cm to 2*1011 [Omega]cm, and containing a liquid crystal layer sandwiched by a substrate having a front electrode on the surface and a substrate having a back electrode, wherein the liquid crystal layer is aligned perpendicular to the electrode surface when no voltage is applied, and upon application of a voltage by multiplex driving, the liquid crystal layer in pixels undergoes an alignment change to align parallel to the substrates. By using slits as pixel dividing structures provided on the front of the electrode, one pixel is divided into a plurality of sub-pixels, such that the directions of the alignment change upon application of a voltage are different between adjacent sub-pixels interposing the slits, and the sub-pixels are formed within a range of from 50 [mu]m to 100 [mu]m.

Description

technical field [0001] The present invention relates to a liquid crystal display device. Background technique [0002] The liquid crystal display device has a structure in which a liquid crystal layer is sandwiched between a transparent substrate disposed on the observer side and a transparent substrate disposed on the opposite side of the observer facing the transparent substrate. The liquid crystal layer is composed of, for example, nematic liquid crystal (hereinafter, also referred to as nematic liquid crystal). A patterned transparent electrode made of, for example, ITO (Indium Tin Oxide) or the like is provided on the inner surface of each substrate. An alignment film is provided between the electrodes on each substrate and the liquid crystal layer as a liquid crystal alignment layer for realizing uniform initial alignment of the liquid crystal. Then, according to the electric field applied between the electrodes, the alignment of the liquid crystal layer is changed f...
