摘要:
An active matrix type of twisted nematic liquid crystal display is provided with a lower alignment layer rubbed in rubbing directions RD3, RD4 opposite to each other, an upper alignment layer rubbed in rubbing directions RD5, RD6 opposite to each other, a liquid crystal layer arranged between the lower and upper alignment layers and filled with liquid crystal molecules set in a nematic liquid crystal phase, a pixel electrode and a common electrode for inducing a vertical electric field in the liquid crystal layer, and a source line and gate line driving a switching device for applying an electric potential to the pixel electrode. The rubbing direction on the substrate with the switching device is at an angle of 1.degree.-44.degree. to either the source or gate line. In this case, major axes of a group of liquid crystal molecules arranged above the pixel electrode are twisted in a clockwise direction, and major axes of other group of liquid crystal molecules are twisted in a counterclockwise direction.
