Abstract
A liquid crystal device is constituted by a pair of substrates, a liquid crystal disposed between the substrates, and an optical member having a planar extension in parallel with the substrates and a non-uniform optical anisotropy along the planar extension. As a result, it is possible to realize a liquid crystal device capable of irregularity-free optical modulation, particularly a liquid crystal display device capable of providing display images with improved contrast and viewing angle characteristic.
