When a structural examination of the formed layer 14 was carried out using a polarizing microscope, linear chiral smectic C phases along the x direction of FIG. 2 were present at the surface of the layer 14 (the x-y plane of FIG. 2). Characteristic dechiralization lines occurred at regula...
The present invention is further detailed as below. A cellulose triacetate film has been applied to a protective film of a polarizing plate because of its good transparency, free of optical strain (low retardation) and excellent adhesion to a polarizer. It is common practice that a plasticizer i...
Particles in a film are observed under a scanning electron microscope and the circumscribed circle diameters of the particles are taken as a particle size of the primary or secondary particles. A total of 200 particles at different sites are observed to take the average value thereof as an ...
