1. An active matrix liquid crystal display, comprising:

  • a pair of substrates with a liquid crystal layer between said substrates;

    a pixel electrode and a common electrode having a common longitudinal axis and that are arranged and adapted to generate an electric field parallel to said substrates in said liquid crystal layer, said liquid crystal layer having a non-zero initial alignment angle relative to the common longitudinal axis; and

    a thin film transistor having a source electrode and a drain electrode adjacent to a first part of said liquid crystal layer, said source and drain electrodes being arranged and adapted so that an electric field generated between said source and drain electrodes is one of substantially parallel to and perpendicular to the non-zero initial alignment angle, whereby an alignment of the first part of said liquid crystal layer does not change when an electric field is generated between said source and drain electrodes.
