US 2006/0152660 A1 · Liquid crystal display apparatus

Abstract

A liquid crystal display apparatus comprising a first substrate with pixel electrodes formed in regions surrounded by a plurality of scanning lines and signal lines, a second substrate on which a transparent electrode is formed, orientation controlling means formed at least on either the first substrate or the second substrate, alignment films deposited on both substrates to which vertical treatment is applied, and a liquid crystal layer having negative dielectric anisotropy, which is sandwiched between both substrates, wherein liquid crystal molecules are vertically aligned when no electric field is applied to the liquid crystal layer, and tilt to be aligned in directions controlled by the orientation controlling means when electric field is applied to the liquid crystal layer, whereby the orientation controlling means is positioned to be approximately linearly symmetrical by using a scanning line and a signal line as boundaries such that the position of the orientation controlling means in relation to pixels adjacent to each other along the scanning line differs from its position in relation to pixels adjacent to each other along the signal line.
