Provided is an image display mirror that includes a half mirror and an image display apparatus, reduces an influence of a reflected image provided by the half mirror, and is excellent in visibility of an image displayed on the image display apparatus. The image display mirror for a vehicle includes a first polarizing plate, a half mirror, and an image display apparatus in the stated order from a viewer side. In one embodiment, the first polarizing plate includes a polarizer, and the direction of the polarizer of the first polarizing plate is set so that the transmittance of light output from the image display apparatus that is transmitted through the first polarizing plate becomes maximum.

Provided is an image display mirror that includes a half mirror and an image display apparatus, reduces an influence of a reflected image provided by the half mirror, and is excellent in visibility of an image displayed on the image display apparatus. The image display mirror for a vehicle includes: a circularly polarizing plate arranged attachably and removably; a half mirror; and an image display apparatus in the stated order from a viewer side. In one embodiment, attached and removed states of the circularly polarizing plate are switched when an image is displayed on the image display apparatus and when the image is not displayed thereon, and when the image is displayed, the circularly polarizing plate is arranged between the half mirror and a viewer.

An image display mirror for a vehicle includes a first polarizing plate arranged so as to be rotatable in a plane, a half mirror having a reflection axis and configured to reflect polarized light, and an image display apparatus in the stated order from a viewer side, in which: the first polarizing plate has a polarizer; a rotation of the first polarizing plate changes an angle of an absorption axis of the polarizer relative to a reflection axis of the half mirror when an image is not displayed on the image display apparatus and when the image is displayed thereon; when the image is not displayed, the absorption axis of the polarizer and the reflection axis of the half mirror are perpendicular to each other; and when the image is displayed, the absorption axis of the polarizer and the reflection axis of the half mirror are parallel to each other.
