Abstract

An LCD (Liquid Crystal Display) including two substrates sandwiching an LC layer therebetween, and causing a plurality of different kinds of regions to coexist in the LC layer is disclosed. An electrode formed with an aperture is provided on at least one of the substrates. A second electrode is also provided on the same substrate as the above electrode in alignment with the electrode. A voltage higher than a voltage to be applied between the electrode with the aperture and a counter electrode facing it is applied between the second electrode and the counter electrode, thereby controlling the rising direction of LC molecules. The LCD is easy to produce and achieves a great viewing angle. In addition, the LC contains a polymer in order to fix the rising directions of the LC molecules.

Dependent claims

A method of producing an LCD, comprising the steps of:

preparing an empty panel comprising two substrates, a first electrode provided on at least one of said two substrates and formed with an aperture, and a second electrode provided on the one substrate in alignment with said first electrode;
injecting LC into said empty panel;
and
cooling said empty panel from a temperature higher than an isotropic phase-LC layer transition temperature of LC to a temperature lower than the transition temperature while applying a voltage, higher than a voltage to be applied between said first electrode and a third electrode facing said first electrode between said second electrode and said third electrode.
