ABSTRACT:
A liquid crystal display device comprises two parallel substrates holding a liquid crystal material filling space between two parallel substrates, wherein one of the two parallel substrates is provided, for each picture element, with a transparent electrode and a lightshielding layer which has an opening located inside the outer periphery of the transparent electrode as observed from a direction perpendicular to the two substrates, and the lightshielding layer is designed so that the distance from an outer periphery of the transparent electrode to an outer periphery of the opening is set substantially larger on the side where rubbing of one substrate is started than on the side where the rubbing is ended, whereas it is set substantially larger on the side where the rubbing of the other substrate is ended than on the side where the rubbing is started as observed from a direction perpendicular to the two substrates.
