Definitions

  • the present invention relates to a laminate containing a vertically oriented liquid crystal cured film, an elliptical polarizing plate including the laminate, and an organic EL display device. It also relates to a composition for forming a vertically oriented liquid crystal cured film that can be used to form the laminate.
  • Ionic compounds generally have a counter anion.
  • the anion component that becomes the counter ion of the cation component include an inorganic anion and an organic anion. Of these, organic anions are preferable because orientation defects of the polymerizable liquid crystal compound are unlikely to occur. It should be noted that the cation and the anion do not necessarily have to have a one-to-one correspondence.
  • the horizontal alignment film can be appropriately selected from materials having a horizontal alignment restricting force that orients the polymerizable liquid crystal compound in the horizontal direction with respect to the plane of the coating film.

Abstract

La présente invention aborde le problème de la fourniture d'un produit en couches qui présente une force de pelage de substrat optimale et qui est obtenu par stratification, à l'aide d'une force adhésive optimale, d'un substrat et d'un film durci de cristaux liquides alignés perpendiculairement qui est formé sans film d'alignement vertical. La présente invention concerne un produit en couches qui comprend un substrat et un film durci de cristaux liquides alignés perpendiculairement qui est adjacent au substrat. Le film durci de cristaux liquides alignés perpendiculairement est un produit durci d'une composition de cristaux liquides polymérisable contenant au moins un type de promoteur d'alignement vertical et au moins un type de composé de cristaux liquides polymérisables, et est un film durci de cristaux liquides dans lequel le composé de cristaux liquides polymérisable est durci dans un état qui est aligné dans une direction perpendiculaire à une surface plane du film durci de cristaux liquides. Le produit en couches satisfait la formule (1). Formule (1) : 0,02 < P < 1,00 (N/25 mm) [Dans la formule (1), P est la force de pelage de substrat (N/25 mm) au niveau d'une interface entre le film durci de cristaux liquides alignés perpendiculairement et le substrat qui constituent le produit en couches lorsque le substrat est pelé à une vitesse de 300 mm/min.]
