Carry out.
The evaluation of coating is visually observed by the coated surface of the substrate to subsidiary liquid crystal orientation film obtained above
Come carry out.Specifically, coated surface is visually observed under sodium vapor lamp, confirms the presence or absence of pin hole.As a result, by any real
Apply the liquid crystal orientation film that example obtains and do not observe pin hole on coated surface, obtain the excellent liquid crystal orientation film of film.
" evaluation (normal cells) of the uneven characteristic of expression of the adjacent edges of liquid crystal cells "
The aligning agent for liquid crystal obtained in aftermentioned embodiment and comparative example is pressurizeed with aperture for 1 μm of molecular filter
Filtering, and be spin-coated on the substrate of subsidiary ITO electrode clean with pure water and IPA (indulging 40mm × horizontal 30mm, thickness is
On ito surface 0.7mm), heated 5 minutes with 100 DEG C on hot plate, baking oven is cleaned with 230 DEG C of heating with thermal cycle type
Processing 30 minutes, so as to obtain the ito substrate for the liquid crystal orientation film that subsidiary thickness is 100nm.It should illustrate, for embodiment 7
With the aligning agent for liquid crystal of embodiment 11, with above-mentioned " evaluation of the ink-jet application of aligning agent for liquid crystal " identical bar
Substrate is made under part, and (substrate has used the substrate of the subsidiary ITO electrode cleaned with pure water and IPA same as described above
(vertical 40mm × horizontal 30mm, thickness are 0.7mm)), thereafter, clean baking oven with thermal cycle type and heated 30 minutes with 230 DEG C, from
