Summary: | The present invention provides a method for manufacturing a thin phase plate with no appearance defects and with high performance. First, as shown in Fig. 1A, a solution of a liquid crystalline compound is applied to a transparent base (1) and dried, or a melted liquid crystalline compound is applied to a transparent base (1), thereby forming a liquid crystalline compound-containing layer (2a). Then, as shown in Fig. 1B, the liquid crystalline compound-containing layer (2a) is turned liquid crystalline or liquefied to be a melted layer (2b). An alignment substrate (3) is brought into contact with the melted layer (2a) to align the liquid crystalline compound in a specific direction. Thereafter, as shown in Fig. 1C, the melted liquid crystalline compound-containing layer (2b) is solidified, and the alignment substrate (3) is removed, thus manufacturing a phase plate (4) composed of a transparent base (1) and an optically anisotropic layer (2c). |
