    摘要： A cellulose acylate film is provided and includes a cellulose acylate as a polymer component. The cellulose acylate is a fatty acid ester of cellulose, obtained by substituting a hydroxyl group of cellulose with an acetyl group or an acyl group with 3 or more carbon atoms. The cellulose acylate film is a film stretched substantially by 10% or more in a casting direction or in a transversal direction to the casting direction, the film having a linear thermal expansion rate D(MD) in a casting direction (machine direction) and a linear thermal expansion rate D(TD) in a transversal direction to casting direction (i.e., perpendicular direction to casting direction) in a specified relationship. A polarizing plate utilizing such film and a liquid crystal display equipped with such polarizing plate are provided.

    摘要： The present invention provides an optically anisotropic element to be used for improvement of visual angle characteristics for display contrast and display color of TN type liquid crystal display element, and to a method for manufacturing the same. The optically anisotropic element has a liquid crystal display element, which comprises a liquid crystal cell, in which a twist nematic liquid crystal is squeezed between two electrode substrates and two polarizing elements disposed on both sides thereof, said optically anisotropic element being disposed between said liquid crystal cell and said polarizing element, whereby it has sheet-like structure and exhibits negative uniaxial property and is arranged in such manner that its optical axis is neither perpendicular nor in parallel to sheet surface, for example, it is inclined at an angle of 10.degree. to 40.degree. from a direction perpendicular to sheet surface. As the result, phase difference caused by the liquid crystal cell CE with respect to oblique incident light is compensated by phase difference of the optically anisotropic element RF, and a liquid crystal display element of high quality with no dependence on visual angle can be obtained.
