摘要： The curing, by UV-light irradiation, of a sealing resin after injecting liquid crystal is made reliable. The display characteristics and the like of an in-plane electric field mode liquid crystal element are improved. To resolve these problems, the viscosity of the sealing resin is lowered, while bubbles mixed in the sealing resin are eliminated by ultrasonic waves, for example. Also, a means for eliminating ions and charges in the liquid crystal layer is devised.

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.

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.
