<P>PROBLEM TO BE SOLVED: To provide a photo-alignment film excellent in photo-alignment of a lyotropic liquid-crystalline dichroic compound, to provide a manufacturing method of the photo-alignment film, and to provide a manufacturing method of a micro-pattern polarizing element using the photo-alignment film. <P>SOLUTION: In a manufacturing method of the polarizing element, a low-molecular material having a photo-alignment group in the molecule is mixed with another low-molecular material having a similar photo-alignment group of a half or double length of the low-molecular material, thereby, an amorphous thin film is formed on a substrate, linearly polarized light is irradiated to the thin film and, subsequently, a dichroic molecular solution is applied by using a printer having a low printing pressure such as a roll coater, a flexo printer and a screen printer. <P>COPYRIGHT: (C)2007,JPO&INPIT |
