Abstract: This liquid crystal display device has a plurality of pixels. Each pixel in the plurality of pixels includes first to fourth alignment regions; these first to fourth alignment regions are arranged in the longitudinal direction of the pixels, and the difference between any two alignment orientations in the first to fourth alignment regions is approximately equal to an integer multiple of 90 degrees. Of the pre-tilt angles defined by a first alignment film and a second alignment film in each of the first to fourth alignment regions, one pre-tilt angle is less than 90 degrees and the other pre-tilt angle is substantially 90 degrees. The optical alignment film is formed using a polymer having an optical alignment group in the side chain, and the content of the optical alignment group in the side chain of the polymer is less than 1.1 mmol/g.

Abstract: A method for forming a uniformly mixed fibrous mat which comprises feeding a continuous high tensile modulus reinforcing fibrous material and a pre-cut thermoplastic fibrous material with a lower melting point or softening point than the temperature at which the reinforcing fibrous material melts or is damaged to a rotating rotor which is provided with projections to thereby cut the continuous fibrous material and pluck the pre-cut fibrous material, dispersing the thus treated fibrous materials into an air flow to mix the same and thereafter collecting the resulting mixed materials on a net to yield the mat. The product can thereafter optionally be compressed under heat to melt only the thermoplastic fibrous material to thereby consolidate the mat.
