That is, a coating film made of a photo-alignment material is provided on a substrate, and two types of polarized light having different polarization directions are irradiated on the coating film. Then, a photo-alignment film is obtained as an alignment material in which two types of liquid crystal alignment regions having different liquid crystal alignment control directions are formed.

Abstract
Description
そして、観察者がメガネを着用して3D画像を観察するディスプレイの方式の1つとしては、円偏光メガネ方式等が知られている(例えば、特許文献1を参照。)。
一方、液晶パネルの液晶を配向させるためには、通常、光配向性の配向材の表面のみを二量化反応させればよい。
しかし、上述のアクリル樹脂等の従来材料を用いて配向材に重合性液晶溶液に対する耐性(溶剤耐性)を発現させようとすると、配向材の内部まで反応を進行させる必要があり、より多くの露光量が必要となる。その結果、従来材料の配向感度は非常に小さくなってしまうという問題があった。
(A)光配向性基と、ヒドロキシ基、カルボキシル基、アミノ基およびアルコキシシリル基から選ばれるいずれか1つの置換基とを有する化合物、
(B)アミド基の窒素原子のうちの少なくとも一部がアルコキシメチル化またはアルキルチオメチル化されたポリアミド、及び
(C)架橋触媒、を含有することを特徴とする硬化膜形成組成物に関する。
