Manufacture with the so-called friction treatment of a direction wiping Deng cloth.
In the orientation process of liquid crystal orientation film, surface to film carries out friction treatment is simple and productivity is excellent
Different industrial useful method.But, due to the high performance of liquid crystal display cells, high-precision densification,
The requirement maximized more improves, the surface-defect of the alignment films therefore produced by friction treatment, dirt, machine
The various problem days such as impact produced by tool power or electrostatic and the inhomogeneities in orientation process face
Become obvious.
The instead method of friction treatment, it is known that the light of liquid crystal aligning energy is provided by irradiating polarization ray
Alignment method.
Process about the liquid crystal aligning utilizing optical alignment method, it is proposed that utilize process, profit that photoisomerization reacts
With the process of photo-crosslinking, the process etc. that utilizes photolysis reactions.
On the other hand, in the case of polyimides is used for light orientation liquid crystal orientation film, from other feelings
Condition is compared to be had the aspect of more high-fire resistance and sets out, its serviceability Worth Expecting.
Thus, KR published patent the 10-2014-0063795th (2014.05.27 is open) discloses and can carry
High anisotropy and suppress the manufacture method of the uneven liquid crystal orientation film produced because of process.
Although above-mentioned prior art can improve the anisotropy of the liquid crystal orientation film utilizing optical alignment method to obtain,
And that suppresses to produce in processing procedure is uneven, but conventional solvent exist cannot meet simultaneously cleaning and
The problem that the polyimides of light orientation does not occur swelling feature.
