ABSTRACT:
A liquid crystal device, in which an orientation film does not deteriorate over time, contrast decreases slightly during longterm use, the axial orientation in the horizontal direction is high, and superior display quality is exhibited, and electronic equipment therewith are disclosed. A liquid crystal light valve employing a liquid crystal device is also disclosed, in which a pair of substrates facing each other; a liquid crystal layer interposed between the pair of substrates; an electrode formed on each of the substrates; and an orientation film formed on the surface of each of the electrodes are provided on the surface15of the substrate body10A, plural grooves16are formed in parallel, in each of the grooves, concave-convex portions10aare formed, which periodically vary along an axial orientation direction Ax of the liquid crystal and have a sawtoothed cross-sectional form along the direction Ax, and between an opening16aof the groove16and each of the top parts18of the concave-convex portions10a, a height difference G is provided.
