Height, therefore influenced caused by surface-defect, hair dirt, mechanical force or the electrostatic as the alignment films of friction treatment generation, Yi Jiqu
Various problem such as the inhomogeneities into process face becomes clear day by day.
As the method for replacing friction treatment, it is known that provide the light orientation of liquid crystal aligning energy by irradiation polarization ray
Method.
It is handled about using the liquid crystal aligning of optical alignment method, proposes the processing using photoisomerization reaction, handed over using light
Join the processing of reaction, utilize processing of photolysis reactions etc..
On the other hand, in the case where polyimides is used for light orientation liquid crystal orientation film, from compared with other situations
It sets out in terms of with more high-fire resistance, serviceability is worthy of expecting.
KR published patent the 10-2014-0063795th (2014.05.27 is disclosed), which discloses, as a result, can be improved respectively
Anisotropy and the manufacturing method for inhibiting the non-uniform liquid crystal orientation film generated by processing.
Although the above-mentioned prior art can be improved the anisotropy of the liquid crystal orientation film obtained using optical alignment method, and press down
What is generated in treatment process processed is uneven, but previous solvent has the polyimides that can not meet cleaning and light orientation simultaneously
The problem of feature not being swollen.
