| 1. A liquid crystal display comprising:
a pair of substrates arranged opposite to each other;
electrodes respectively formed on opposite surfaces of the pair of substrates;
an alignment regulating structural member which includes at least one of a linear projection arranged on the electrode and
a slit portion formed by removing a part of an electrode material of the electrode, and is formed on at least one of the pair
of substrates; and
a liquid crystal layer sealed between the substrates and having a negative dielectric anisotropy, in which alignment control
is made such that when a voltage is applied to the electrodes, an alignment orientation of a liquid crystal domain in a region
adjacent to the alignment regulating structural member is different from an extending direction of the alignment regulating
structural member by approximately 45°, and at a time of no voltage application, a liquid crystal molecule of a region where
the alignment regulating structural member does not exist is substantially vertically aligned, and a liquid crystal molecule
on the alignment regulating structural member or on its opposite portion is un-vertically aligned.
