Abstract

A liquid crystal display device includes: first and second substrates disposed to be opposed to each other; a liquid crystal layer held between the first and second substrates, formed of a p-type liquid crystal material, and configured to take a vertical alignment in a state in which no electric field is applied; one or a plurality of linear pixel electrodes provided on the first substrate; a first common electrode provided on the first substrate, and formed in a manner to surround or sandwich the pixel electrode with a predetermined spacing; and a second common electrode provided on the second substrate, having substantially the same planar shape as the first common electrode, and formed such that at least a part of the second common electrode overlaps the first common electrode in planar projection.
