IMAGE DISPLAY MIRROR FOR A VEHICLE
First Claim
1. An image display mirror for a vehicle, comprising a first polarizing plate arranged so as to be rotatable in a plane, a half mirror having a reflection axis and being configured to reflect polarized light, and an image display apparatus in the stated order from a viewer side, wherein:
- 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.
