摘要： A method is provided by which a highly functional thin retardation plate with no appearance defect can be produced. First, as shown in FIG. 1A, a solution of a liquid crystalline compound is applied on a transparent base 1 and dried, or alternatively, a liquid crystalline compound on the melt is applied on the transparent base 1, and thus a liquid crystalline compound-containing layer 2a is formed. Then, as shown in FIG. 1B, the liquid crystalline compound-containing layer 2a is brought to a liquid crystal state or a liquid state so as to form a layer 2b. An alignment substrate 3 is brought into contact with an upper portion of the layer 2a so that the liquid crystal compound is aligned in a particular direction. Then, after the liquid crystalline compound is aligned in the particular direction, as shown in FIG. 1C, the liquid crystalline compound-containing layer 2b on the melt is solidified, and the alignment substrate 3 is removed. Thus, a retardation plate 4 composed of the transparent base 1 and an optically anisotropic layer 2c is produced.

摘要： An elliptically polarizing plate comprising a retardation film having a film comprising a polymer which has, as its main chain, a polyol skeleton having a side chain substituted with at least one chemical group selected from the group consisting of an aromatic carbonyl group, an aryl-substituted lower alkylcarbonyl group, and an unsaturated aliphatic carbonyl group, the chemical group being bonded to an oxygen atom in the polyol skeleton side chain, and a polarizer stacked over the retardation film, wherein the polarizer is made of a coating film obtained by applying a dichromatic colorant. As the dichromatic colorant, an organic colorant represented by (chromogen)(SO3M)n wherein M represents a cation is used. The elliptically polarizing plate has a good visibility in the range of visible rays and can be made thin and light.

摘要： A modified polymer which can serve as a raw material of novel reverse dispersion retardation films is provided, the modified polymer having no need to select a plurality of monomers or polymers in order to realize a reverse dispersion and having no problems concerning glass transition temperature or the like in drawing treatment. A polymer having a polyol skeleton as its main chain is caused to react with a compound for modification such as an aromatic carboxylic acid hydride. Through this reaction, a modified polymer in which a chemical group such as an aromatic carbonyl group is bonded to an oxygen atom in a side chain of the polyol skeleton is prepared. For example, polyvinyl alcohols and benzoyl chloride can be used as the polymer and the compound for modification, respectively. The chemical group may be a benzoyl group. When this modified polymer is formed into a film and then subjected to drawing treatment, a retardation film which exhibits a reverse wavelength dispersion characteristic can be obtained.
