Abstract:
A liquid crystal display comprising:a first and a second substrate opposed to each other;an array of pixel electrodes overlying said first substrate, each of said pixel electrodes defining a pixel area and having an active element for applying a voltage to said pixel electrode;at least one counter electrode overlying said second substrate and opposing said array of pixel electrodes;a first and a second orientation film overlying said pixel electrode and said counter electrode, respectively, at least one of said first orientation film and said second orientation film being subjected to a divided orientation alignment in different directions to divide each said pixel area at a boundary into a first area and a second area;a plurality of gate bus lines each for supplying a signal to control electrodes of a row of said active elements and a plurality of drain bus lines each for supplying a voltage to a column of said pixel electrodes through corresponding said active element;liquid crystal interposed between said first orientation film and said second orientation film, said first area and said second area defining a first domain and a second domain, respectively, for said liquid crystal;a first shield film, having at least a first part thereof disposed in alignment with a region corresponding to at least one of said gate bus lines and having at least a second part thereof disposed in alignment with a region corresponding to at least one of said drain bus lines, for shielding a disclination deformed by a lateral electric field acting between said pixel electrode and said at least one of said gate bus lines and drain bus lines during operation of said liquid crystal display cell; anda second shield film having at least a first part thereof disposed in alignment with a region adjacent to at least one of said gate bus lines, having at least a second part thereof disposed in alignment with a region adjacent to at least one of said drain bus lines, and having at least a third part thereof disposed in alignment with said boundary, for shielding a disclination deformed by a lateral field acting between said pixel electrode and said at least one of said gate bus lines and drain bus lines during operation of said liquid crystal display cell,wherein said first shield film overlies said second substrate, andwherein said second shield film is formed on said second substrate.
