Liquid crystal display device with two different pre-tilt angles adjacent on one substrate |
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.
