    摘要： A liquid crystal display includes two substrates and a liquid crystal layer sandwiched between the substrates and performs display by changing the orientation of the liquid crystal layer from a splay orientation to a bend orientation. Application of a voltage of less than a threshold voltage to the liquid crystal layer allows the liquid crystal layer to have a region where liquid crystal molecules parallel to the substrates predominantly lie on one substrate side and a region where those liquid crystal molecules predominantly lie on the other substrate side, and the two regions are present in substantially equal proportions. In a similar liquid crystal display, the absolute value of a pretilt angle of the liquid crystal molecules in the vicinity of one substrate differs from the absolute value of a pretilt angle of the liquid crystal molecules in the vicinity of the other substrate, and at least one of the substrates is provided with a bend transition nucleus induction means. As a method for making a difference between the pretilt angles, alignment films made of the same material are formed on the substrates, and then only one of the substrates is subjected to an alignment process or both substrates are subjected to the alignment process under different conditions.

    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.

    摘要： A liquid crystal display device including a liquid crystal panel. The liquid crystal device is made up of first and second substrates, a first alignment layer formed on a surface of the first substrate so as to have a first pre-tilt angle, a second alignment layer formed on a surface of the second substrate so as to have a second pre-tilt angle which is smaller than the first pre-tilt angle, a third alignment layer formed on the surface of the second substrate so as to have a third pre-tilt angle which is greater than the first pre-tilt angle, and nematic liquid crystal material filled in a space between the first and second substrates. The liquid crystal panel would be oriented so as to have a helical structure extending in a predetermined direction by the effect of the pre-tilt angles if nematic liquid crystal material having no twisting power were to be filled in a space between the first and second substrates, but the nematic liquid crystal material employed is of a kind effective to render the liquid crystal panel to be oriented so as to have a helical structure extending in a direction counter to the predetermined direction.
