Liquid crystal alignment member for spatial light phase modulation, spatial light modulation element and stereoscopic display device

A liquid crystal alignment member for spatial light phase modulation comprising:

• a base portion including a silicon substrate, and pixel electrodes arranged in a matrix with a period of 3 μm or less, disposed on a surface of the silicon substrate;
• a lattice-shaped wall structure in which a plurality of linear convex part is combined, arranged on the base portion and configured by a dielectric material;
• a base layer configured by the dielectric material, connected to the lattice-shaped wall structure;
• and
• a plurality of liquid crystal-filling microspace for filling a liquid crystal, that is separated from each other by the lattice-shaped wall structure, and is disposed on the base layer, wherein
