Abstract
A liquid crystal display device comprises a first substrate including a first insulation substrate, and rectangular pixel electrodes provided in a matrix on the first insulation substrate and elongated in a first direction, a second substrate opposing the first substrate, and including a second insulation substrate, a counter electrode on the second insulation substrate, and projections on the counter electrode, elongated in a second direction intersecting the first direction, and a liquid crystal layer held between the first and second substrates. The projections extend through pixel regions defined by the pixel electrodes and counter electrode, and are formed asymmetrical with respect to a first imaginary line passing through centers of opposite short sides of each pixel electrode and extending in the first direction, and with respect to a second imaginary line passing through centers of opposite long sides of each pixel electrode and extending in the second direction.
