A field effect mode liquid crystal display element displaying dot matrix pattern includes a cut-out portion formed either in the upper or lower electrode so that liquid crystal display molecules can be prevented from being inversely oriented at the edge of such a portion where these electrodes cross each other as might otherwise occur. The cutout portion prevents the liquid crystal display molecules from being inversely oriented at the edge of such a portion where these electrodes cross each other, thus significantly improving display quality. In addition, since such a cutout portion is provided by merely cutting off part of an electrode to prevent the unwanted inversion of LCD molecules during orientation, no specific signal process is required.

Edge domain-free liquid crystal display of dot matrix type

A pair of polarizers are respectively attached to a pair of substrates forming a twisted nematic field effect mode liquid crystal display. An orientation control film is disposed on each of the pair of substrates to orient liquid crystal molecules of a liquid crystal material in a desired direction. Each of the pair of polarizers is attached to an outer surface of the respective substrates such that the plane of polarization of each of the polarizers is not in parallel with or perpendicular to a direction oriented by the orientation control film.
