ABSTRACT:
A liquid crystal element comprises a cell structure where a liquid crystal is disposed between a pair of electrode substrates, a first electrode substrate of said pair of electrode substrates having a first resin layer formed at the surface contacting the liquid crystal of the first electrode substrate by thermal curing resulted from dehydration ring closure, the first resin layer being able to control orientation of the liquid crystal, and a second electrode substrate having a second resin layer formed at the surface contacting the liquid crystal of the second electrode substrate by thermal curing at a temperature lower than that at which the first resin layer is formed, the second resin layer being able to control orientation of the liquid crystal.
