1. 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 positive 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;

    two sets of pixel electrodes, each having a comb like shape and interdigitally aligned with one another, one set of said pixel electrodes being connected to a common electrode;

    an active element connected to said pixel electrodes, said scanning lines and said video signal lines, respectively;

    wherein each of said pixel electrodes is 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 of said pixel electrodes is within an angle ranging between plus 1-30 degrees relative to the alignment direction of the liquid crystal, while the second direction of the pixel electrodes is within an angle ranging between minus 1-30 degree relative to the alignment direction with substantially the same absolute angle with that of the first direction, thereby making the first and second directions symmetrical relative to said alignment direction.
