Patent ID: 7098980

Claim:
An active matrix liquid crystal display device, comprising: a pair of substrates, at least one of which is transparent; a liquid crystal composite layer provided between said substrates and having a negative dielectric constant; a plurality of scanning lines and video signal lines provided in a matrix manner on a surface of one of said substrates facing the other substrate; a plurality of pixel electrodes each having a comb like shape; a plurality of common electrodes each having a comb like shape and connected to a common line, wherein said pixel electrode and the common electrode are interdigitally aligned with one another in each pixel; active elements connected to said pixel electrodes, said scanning lines and said video signal lines, respectively; wherein each of said pixel electrodes and common electrodes are inclined in first and second directions to form a zigzag shape which is symmetrical relative to the alignment direction of the liquid crystal, where the first direction is within an angle ranging between plus 60–120 degrees except 90 degrees relative to the alignment direction of the liquid crystal, while the second direction is within an angle ranging between minus 60–120 degrees except 90 degrees relative to the alignment direction.
