摘要：A kind of production optical compensating film is provided, stretches celluloseacetate film, it is 2. that cellulose acetate film, which has water content,0 to 20.0% weight%, wherein the acetyl value of cellulose acetate film is from 57.0% to 62.5%; The opticalcompensation films produce manufacture optical compensation films according to thepresent invention; Namely laminated polarizing plate includes optical compensating filmand polarizing film; Show that a kind of includes at least one light compensation film andpolarizer with image. Manufacture optical compensating film according to the presentinvention, light compensation film can be stable at commercial scale with the big NZfactors and with good view angle characteristics (plates of especially λ/4 have the phasedifferences of λ/4 in wide wave-length coverage). Particularly, in the method, the light
compensation film that the NZ factors generate, can control well, postpone it withoutchanging, therefore this method guarantees that plant-scale production lightcompensation film has improved view angle characteristics. In addition, image display,especially reflection or half transmission liquid crystal display device and Organnicelectroluminescent device include this optical compensation films with image display orincluding polarizing film made according to the method for the present invention thereare optical compensation films all to have good view angle characteristics.
