The present invention provides a variable transmittance optical laminate and a use thereof. The variable transmittance optical laminate comprises: a first polarizing plate; a first transparent conductive layer formed on one surface of the first polarizing plate; a second polarizing plate facing the first polarizing plate; a second transparent conductive layer formed on one surface of the second polarizing plate and facing the first transparent conductive layer; and a liquid crystal layer provided between the first transparent conductive layer and the second transparent conductive layer, the first transparent conductive layer and the second transparent conductive layer containing a conductive polymer, the liquid crystal layer containing a polymer network and a liquid crystal compound, the liquid crystal compound being arranged in a uniform initial orientation. The variable transmittance optical laminate of the present invention can prevent the problem of damage to an alignment film or difficulty in maintaining an in-plane constant optical color due to conventional use of a spacer, and thus can improve driving stability compared to conventional optical laminates.

    本发明提供透透过率可变光学层叠体及其用途,上述透过率可变光学层叠体包含:第一偏光板;第一透明导电层,其形成于上述第一偏光板的一面上;第二偏光板,其与上述第一偏光板相对;第二透明导电层,其形成于上述第二偏光板的一面上,且与上述第一透明导电层相对;以及液晶层,其设置于上述第一透明导电层与第二透明导电层之间,上述第一透明导电层和第二透明导电层包含导电性高分子,上述液晶层包含高分子网络和液晶化合物,上述液晶化合物以均匀的初始取向排列。本发明的透过率可变光学层叠体能够防止以往使用间隔物所致的取向膜损伤或难以保持面内恒定的光学颜色的问题,由此与以往光学层叠体相比,能够提高驱动稳定性。
