Abstract
A liquid crystal display device comprises a substrate, two electrode-attached substrates formed by sequentially superposing electrode layers and orientation layers on the substrate and disposed so as to oppose the orientation layers to each other across a gap, and a liquid crystal composition placed in the gap and consequently interposed between the two electrode-attached substrates, which liquid crystal display device is characterized in that the orientation layers is furnished with multiply divided liquid crystal orientation areas and the orientation areas severally have directions of orientation set either in a radial pattern or in the shape of concentric rings.
