Poval family resin is provided with attached dichroism pigment and the polarizing membrane thereon is a protective membrane composed of cycloolefin family resin with the help of bonding agent. During the production of the polarizing membrane, after the above mentioned protective membrane is contacted with a mixed organic solvent without solute in a manner with no more than 0.5% turbidity value, the protective membrane is attached to the polarizing membrane. The mixed organic solvent is the mixed solvent of the following solvents: the organic solvent(good solvent),whereby the resin is changed because of the contact, and the organic solvent (bad solvent), whereby the resin is substantially changed not because of the contact. The mixed organic solvent can be replaced by the individually used alicyclic hydrocarbon, but the bad solvent, which is mixed with the alicyclic hydrocarbon, is useful. |
