A LIQUID CRYSTAL ALIGNMENT FILM AND A LIQUID CRYSTAL DISPLAY ELEMENT USING THE SAME |
摘要 |
[Problem] The purpose of the present invention is to provide a method for developing a large anchoring energy by simple processes. [Solution] There is provided a method for manufacturing a liquid crystal alignment film, comprising: a process (I) of mixing a solvent with a photoresponsive polymer to prepare a photoresponsive polymer solution; a process (II) of coating the photoresponsive polymer solution on a substrate, followed by drying at 50 to 100° C. for 1 to 3 minutes and then drying at 120° C. to 180° C. for 5 to 75 minutes to form a coating film; and a process (III) of adjusting a temperature of the coating film while the coating film is irradiated with a light of 200 to 350 nm to 40° C. to 100° C. |
