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.
