Abstract
The liquid crystal display device of the present invention includes: a first substrate; a second substrate; a liquid crystal layer sandwiched by the first and second substrates; and wall structures formed on a surface of the first substrate facing the liquid crystal layer for dividing the liquid crystal layer into a plurality of liquid crystal regions. Liquid crystal molecules in the plurality of liquid crystal regions are aligned axially symmetrically with respect to an axis vertical to a surface of the first substrate. The liquid crystal regions have a shape of a polygon having dulled corners. The alignment direction of the liquid crystal molecules in the liquid crystal regions with respect to side faces of the wall structures in the corners changes continuously.
