Non-birefringence optical resin material, a production process therefor and a member for a liquid crystal device using the optical resin material

摘要

A non-birefringence optical resin material is obtained by forming a transparent matrix from a polymeric resin having an orientation birefringence with a positive or negative sign, adding a low molecular weight substance exhibiting an orientation birefringence with a sign opposite to that of the orientation birefringence of the polymeric resin for the matrix and thus offsetting the orientation birefringence of the polymeric resin for the matrix with the orientation birefringence of the low molecular weight substance.
