1. A liquid crystal display comprising:

  • a pair of substrates, at least one of which is transparent;

    a liquid crystal layer interposed between said pair of substrates;

    electrodes configured to apply an electric field to liquid crystal molecules in said liquid crystal layer;

    active switching elements connected with said electrodes;

    an alignment film formed on a surface of at least one of said pair of substrates, said surface contacting said liquid crystal layer; and

    an optical device configured to control a transmission of light in cooperation with alignment of said liquid crystal molecules in each pixel, said optical device being located on at least one said pair of substrates;

    wherein said alignment film is subjected to a rubbing treatment with a rubbing strength so that an aligning direction in a plane parallel to the substrate of each liquid crystal molecule in each pixel is ranged between −

    2 degrees to +2 degrees with respect to an average aligning direction of said liquid crystal layer.
