摘要： This invention enables forming a photo-alignment film having a large LC anchoring strength in an IPS type liquid crystal display device. An alignment film is adapted to have a two-layer structure including a photo-alignment film and an alignment film with enhanced film strength. The photo-alignment film is formed of a precursor of polyamide acid ester, 80 percent or more of which is polyamide acid ester including cyclobutane. The alignment film with enhanced film strength is formed of a precursor of polyamide acid. After irradiating the substrate with ultraviolet light for photo-alignment, the substrate is heated. Thus, it is possible to achieve a high LC anchoring strength of the alignment film as the whole for photo-alignment, without degrading the mechanical strength of the alignment film with enhanced film strength.

摘要： An IPS liquid crystal display device intended to prevent generation of second image sticking after generation of initial DC image sticking.An alignment film has a two-layer structure comprising an upper alignment film and a lower alignment film. The upper alignment film is an optical alignment film formed of a polyamide acid ester as a precursor. The lower alignment film has a lower resistance value than the upper alignment film and also has a low photoconductive property. The lower alignment film is formed not using, as a precursor, a polyamide acid using PMDA as the starting material but using, as a precursor, the polyamide acid containing a sulfonic acid group or a carboxylic group, whereby the difference of the resistance between portions undergoing or not undergoing light irradiation in the pixel is decreased and generation of second image sticking can be prevented.
