| 1. A liquid crystal display device comprising:
a pair of spaced and opposed substrates;
an electrode and an alignment layer formed on one of said substrates and on the other substrate of said substrates; and
a liquid crystal filled between said pair of substrates;
wherein said liquid crystal has a dielectric constant of negative anisotropy;
said alignment layers on the one and the other substrates are formed so that one pixel has four regions divided by a crosswire
boundary line in which the alignments of the liquid crystal are mutually different; and
a shading layer is provided to cover the crosswire boundary line,
wherein said shading layer comprises a storage capacity electrode formed on one of said substrates, and having a first portion
extending in a first direction and a second portion extending in a second direction substantially perpendicular to said first
direction.
