Abstract

L'invention concerne un procédé de fabrication d'un film à différence de phase ayant au moins deux couches anisotropes optiques différentes l'une de l'autre. Dans le procédé, une couche de matériau de base composée d'un polymère biréfringent positif est étirée, une solution de polymère biréfringent négatif est appliquée et séchée sur la couche de matériau de base pour former une couche biréfringente négative, puis, un corps laminé de la couche de matériau de base et de la couche biréfringente négative est étiré dans une direction coupant orthogonalement la direction d'étirement de la couche de matériau de base.
