1. A liquid crystal display comprising:

  • two substrates opposite to each other and spaced apart a predetermined distance, each of the substrates having an alignment layer;

    a liquid crystal layer between the two substrates, and having a plurality of liquid crystal molecules; and

    a pair of electrodes formed on one of the substrates;

    wherein each of the alignment layers has a plurality of parallel grooves on its surface for orienting the liquid crystal molecules, therefore, when no voltage is provided, the overall arrangement of the liquid crystal molecules comprises a 90°

    twist;

    when a voltage is applied to the electrodes, an electrical field parallel to the substrate is formed, which rotates and orients the liquid crystal molecules, and makes the arrangement of the liquid crystal molecules homogeneous.
