摘要： PROBLEM TO BE SOLVED: To prevent generation of a second afterimage after generating an initial DC afterimage in an IPS (in-plane switching) system liquid crystal display device.SOLUTION: An alignment layer 113 is formed to have a two-layer structure of an upper alignment layer 1131 and a lower alignment layer. The upper alignment layer 1131 is a photo-alignment layer and is formed of a polyamide acid ester as a precursor. The lower alignment layer 1132 has a resistance lower than that of the upper alignment layer 1131 as well as lower photoconductivity characteristics. The lower alignment layer 1132 is formed, not using a polyamide acid derived from PMDA (pyromellitic dianhydride) as a raw material but using a polyamide acid having a sulfonic acid group or carboxyl group as a precursor. In a pixel, the difference of resistance between a portion irradiated with light and a portion not irradiated with light is decreased, which prevents generation of a second afterimage.
摘要翻译：要解决的问题：为了防止在IPS（平面内切换）系统液晶显示装置中产生初始DC残留物之后产生第二余像。解决方案：取向层113形成为具有上取向层1131和下取向层的双层结构。上取向层1131是光取向层，由聚酰胺酸酯作为前体形成。下取向层1132具有比上取向层1131低的电阻以及较低的光导特性。形成下取向层1132，不使用来自PMDA（均苯四酸二酐）的聚酰胺作为原料，但使用具有磺酸基或羧基的聚酰胺酸作为前体。在一个像素中，照射光的部分与未被光照的部分之间的电阻差减小，这防止产生第二余像。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To form a photo-alignment film having a large anchoring strength in an IPS type liquid crystal display device. SOLUTION: An alignment film 113 is adapted to have a two-layer structure including a photo-alignment film 1131 and an alignment film with enhanced film strength. The photo-alignment film 1131 is formed of a precursor of polyamide acid ester, 80 percent or more of which is polyamide acid ester including cyclobutane. The alignment film 1132 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 anchoring strength of the alignment film as a whole for photo-alignment, without degrading the mechanical strength of the alignment film 1132 with enhanced film strength.
