Abstract
A liquid crystal display apparatus includes a first substrate; a second substrate provided so as to face the first substrate; a vertical alignment type liquid crystal layer provided between the first substrate and the second substrate; a plurality of pixel areas each including a first electrode provided on the first substrate, a second electrode provided on the second substrate, and the liquid crystal layer provided between the first electrode and the second electrode; and a wall structure regularly arranged on a surface of the first electrode closer to the liquid crystal layer. The liquid crystal layer, when being provided with at least a prescribed voltage, forms at least one liquid crystal domain exhibiting a radially inclined orientation in an area substantially surrounded by the wall structure.
