Abstract (en)

[origin: WO9963400A1] A light controlling film (10) is disclosed, comprising a polymerized polymer network varying spatially in a direction normal to the film surface, where the polymerized polymer network is a cross-linked high molecular weight polymeric material mixed with a low molecular weight nematic material exhibiting cholesteric liquid crystal (CLC) order, wherein an electric field impressed in the film controls the reflection bandwidth of circularly polarized light.
