Abstract: An object of the present invention is to provide a transmission decorative film having transparency and capable of applying different visual effects on observation surfaces. The transmission decorative film includes: a linear polarization plate; a first λ/4 plate laminated on one main surface of the linear polarization plate; a first cholesteric liquid crystalline layer laminated on the first λ/4 plate; a second λ/4 plate laminated on the other main surface of the linear polarization plate; and a second cholesteric liquid crystalline layer laminated on the second λ/4 plate, in which the first cholesteric liquid crystalline layer and the second cholesteric liquid crystalline layer respectively have wavelength selective reflectivity and reflect light which is right circularly polarized light or left circularly polarized light at a selective reflection wavelength.

Abstract: The inventions are an optical film containing cellulose acylate and a compound having a structure denoted by General Formula (A) described below, and a polarizing plate and a liquid crystal display device employing the optical film. L represents n-valent connecting group, n represents an integer of greater than or equal to 2, and A represents a heterocyclic group denoted by General Formula (I). R1, R3, and R5 represent a hydrogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, an aryl group, or a heteroaryl group. Here, any one of R1, R3, and R5 is bonded to L.
