    摘要: A transparent product that gives an image only at one side, which can be used for an advertisement on the window or the like, which is a product that has a semi-transmissive-half-reflective layer having transmittance of 30% or higher and a reflectance of 30% or higher, a birefringent layer which is a patterned optically anisotropic layer having two or more regions of different birefringence in the form of a pattern or a driven-type optically anisotropic layer containing a liquid-crystal compound driven by voltage application to control the optical anisotropy, and a polarizing layer in this order and does not have, at the opposite side of the polarizing layer with respect to the birefringent layer, a polarizing layer, is provided.
