1. A liquid crystal panel comprising:

  • a pixel substrate having scanning lines extending in a first direction, signal lines extending in a second direction crossing said scanning lines, switching elements, pixel electrodes arranged in a matrix forming rows in the first direction and columns in the second direction, and an alignment film, wherein each of the pixel electrodes is connected to a corresponding one of said scanning lines and a corresponding one of said signal lines through a corresponding one of said switching elements;

    an opposing substrate having an electrode layer and an alignment film;

    a liquid crystal layer sealed between said pixel substrate and said opposing substrate; and

    a driving system for driving said scanning lines and said signal lines, wherein the molecules of the liquid crystal layer have a negative dielectric anisotropy and incline with a pretilt angle in a range of 3°

    to 10°

    with respect to the direction which is normal to said pixel substrate or said opposing substrate, wherein the alignment direction of the alignment films of said pixel substrate and said opposing substrate is at an angle of about 45°

    with respect to the first direction, and wherein said driving system drives said scanning lines and said signal lines such that adjacent groups of two or more adjacent pixels at least in a row direction are supplied with driving voltages of opposite polarity.
