Abstract
A liquid crystal display device includes: a vertical alignment liquid crystal layer; first and second substrates facing each other with the liquid crystal layer interposed; first and second electrodes arranged on the first and second substrates to face the liquid crystal layer; and at least one alignment film in contact with the liquid crystal layer. A pixel region includes a first liquid crystal domain in which liquid crystal molecules are tilted in a first direction around the center of a plane, and approximately at the middle of the thickness, of the liquid crystal layer responsive to a voltage applied. The first liquid crystal domain is close to at least a part of an edge of the first electrode. The part includes a first edge portion in which an azimuthal direction, perpendicular to the part and pointing toward the inside of the first electrode, defines an angle greater than 90 degrees to the first direction. The first or second substrate has an opaque member including a first opaque portion for selectively shielding at least a part of the first edge portion from incoming light.
