Abstract
An anti-glare mirror with an image display function includes, in this order: an image display device; a circular polarization reflection layer A; a liquid crystal cell; and a linear polarizing plate, in which a phase difference layer such as a ¼ wavelength plate is provided between the circular polarization reflection layer A and the linear polarizing plate, and the circular polarization reflection layer A has a cholesteric liquid crystal layer obtained by curing a coating layer of a liquid crystal composition containing a polymerizable liquid crystal compound.
