    • PROBLEM TO BE SOLVED: To provide an optical article for improving its productivity, and to provide a method for manufacturing the optical article. SOLUTION: In this optical article, a polarizing separation film 13 constituted by laminating high refractive layers and low refractive layers alternately and forming the uppermost surface layer as the high refractive layer is formed in a first light transmissive member 11, and a joint layer 16 is provided between the polarizing separation film 13 and a second light transmissive member 12 and is formed by a plasma polymeric film having the same refractive index as that of the low refractive layer. Consequently, a layer composed of the polarizing separation film 13 and the joint layer 16 has the same film configuration as that of a conventional polarizing separation film, so that optical characteristics of the polarizing separation film 13 is not deteriorated. In addition, since the low refractive layer being the uppermost surface layer in the conventional film configuration is replaced with the joint layer 16 in this optical article, a process for forming the low refractive layer constituting the uppermost surface layer can be eliminated when forming the polarizing separation film and a reflective film in this manufacturing method.

    • 要解决的问题:提供一种用于提高其生产率的光学制品,并提供一种制造该光学制品的方法。 解决方案:在这种光学制品中,在第一透光构件11中形成由交替地层叠高折射层和低折射层而形成最上表面层作为高折射层的偏振分离膜13, 层16设置在偏振分离膜13和第二透光构件12之间,并且由具有与低折射层相同的折射率的等离子体聚合物膜形成。 因此,由偏光分离膜13和接合层16构成的层具有与以往的偏光分离膜相同的膜构造,使得偏振分离膜13的光学特性不劣化。 此外,由于在该光学制品中用作为接合层16的以往的膜构造中的最上表面层的低折射率层被代替,所以当形成极化时可以消除构成最上表面层的低折射层的形成工艺 分离膜和反射膜。 版权所有(C)2011,JPO&INPIT
