Abstract

The invention provides: a composition for forming a cured film, which forms a cured film having excellent photoreaction efficiency, solvent resistance, high adhesion and alignment uniformity; an alignment material for optical alignment; and a phase difference material which is formed using the alignment material. A composition for forming a cured film, which contains (A) a compound that has an optical alignment group and one substituent selected from among a hydroxy group, a carboxyl group and an amino group, (B) a hydrophilic polymer having one or more substituents selected from among a hydroxy group, a carboxyl group and an amino group, and (C) a polymer that is obtained by polymerizing a monomer containing an N-hydroxymethyl compound or an N-alkoxymethyl (meth)acrylamide compound. This composition for forming a cured film additionally contains, if necessary, (D) a crosslinking catalyst. An alignment material is produced by forming a cured film with use of this composition for forming a cured film, while utilizing an optical alignment technique. A phase difference material is obtained by applying a polymerizable liquid crystal over the alignment material and curing the polymerizable liquid crystal thereon.

Description

technical field [0001] The present invention relates to a composition for forming a cured film, an orientation material, and a retardation material. Background technique [0002] In recent years, in the field of displays such as televisions using liquid crystal panels, development of 3D displays capable of viewing 3D images has been progressing as an effort to increase performance. In a 3D display, for example, an image having a three-dimensional effect can be displayed by allowing the viewer's right eye to view a right-eye image and the viewer's left eye to view a left-eye image. [0003] There are various systems for a 3D display displaying a 3D image, and a lenticular lens system, a parallax barrier system, and the like are known as systems that do not require special glasses. [0004] Furthermore, a circularly polarized glasses system is known as one of the systems in which an observer wears glasses to observe a display of a 3D image (for example, refer to Patent Docume...
