Abstract:
It is possible to realize an In-Cell type light polarizer having a high voltage holding ratio (charge holding characteristic) appropriate for an active drive LCD. The In-Cell type light polarizer (5) of active drive LCD is made of a material which is an In-Cell type light polarizer composition containing a pigment and a solvent and having electric conductivity not smaller than 25 mS/cm.
Abstract:
This invention provides a coloring matter for an anisotropic coloring matter film, which has achromatic color, is highly dichroic, and has a high degree of molecular orientation and is formed by a wet film formation method, and a composition for an anisotropic coloring matter film comprising the coloring matter film, an anisotropic coloring matter film comprising this coloring matter, and a polarizing element using the anisotropic coloring matter film. The coloring matter in its free acid form is represented by the following formula (I). (I) wherein A 11 : a (substituted) phenyl group, a (substituted) naphthyl group, or an (substituted) aromatic heterocyclic group; B 11 : a divalent aromatic hydrocarbon group or aromatic heterocyclic group; R 11 and R 22 : H, OH, an (substituted)alkyl group; a (substituted) phenyl group, or an (substituted)acyl group; n': 1 or 2; and m: 0 or 1.
