Title:
光学積層体、その製造方法、並びにこれを用いた偏光板及び液晶表示装置
Document Type and Number:
Japanese Patent JP6481368
Kind Code:
B2
Abstract:
Provided are an optical laminated body including a resin layer on an acrylic base material in which the generation of an interference pattern is suppressed and the adhesiveness between the acrylic base material and the resin layer is improved and a method for efficiently manufacturing the optical laminated body. Provided are an optical laminated body including a resin layer including a binder resin and organic fine particles B on one surface of an acrylic base material including organic fine particles A, in which, in a standard length of 30 μm taken in a direction perpendicular to a thickness direction of the optical laminated body on a cross-section of the optical laminated body in the thickness direction, when an average depth of three deepest troughs selected from plural troughs in an interface between the acrylic base material and the resin layer is considered as a standard depth and then an average height of three highest crests selected from plural crests in the interface is considered as a standard height, a vertical difference between the standard height and the standard depth is in a range of 150 nm to 500 nm, a polarization plate and a liquid-crystal display device using the optical laminated body, and a method for manufacturing the optical laminated body.
