Abstract: A vehicle mirror having an image display function includes an image display device, a circularly polarized light reflection layer, and a front plate formed of glass or plastic in this order. The circularly polarized light reflection layer includes a linearly polarized light reflection plate and a 1/4 wavelength plate from a side of the image display device. The linearly polarized light reflection plate and the 1/4 wavelength plate are directly in contact with each other, or only an alignment layer is included between the linearly polarized light reflection plate and the 1/4 wavelength plate. A method for producing the vehicle mirror includes forming the 1/4 wavelength plate from a composition that is directly applied to the surface of the linearly polarized light reflection plate or that is directly applied to the surface of the alignment layer directly in contact with the linearly polarized light reflection plate.
