Optical compensatory sheet comprising cellulose acetate support and optically anisotropic layer, an ellipsoidal polarizing plate, and a liquid crystal display

   
   

An optical compensatory sheet comprises a cellulose acetate support and an optically anisotropic layer. The optically anisotropic layer contains a discotic liquid crystal molecule. The cellulose acetate support has a Bth.sup.550 birefringence in the range of 0.0007 to 0.004.

Ein optisches Ausgleichsblatt enthält eine Zelluloseazetatunterstützung und eine optisch anisotrope Schicht. Die optisch anisotrope Schicht enthält ein discotic flüssiges Kristallmolekül. Die Zelluloseazetatunterstützung hat eine Doppelbrechung Bth.sup.550 in der Strecke 0.0007 bis 0.004.
