Abstract

A vehicle includes: an image display mirror including a first polarizing plate, a half mirror, and an image display apparatus in the stated order from a viewer side; and a second polarizing plate, in which: the image display mirror is arranged so as to b viewable by a driver of the vehicle; the half mirror is configured to be oriented in different directions between when an image is displayed on the image display apparatus and when the image is not displayed thereon; the second polarizing plate is arranged so that light transmitted through the second polarizing plate reaches a first polarizing plate side of the image display mirror when the image is displayed on the image display apparatus; and the vehicle is configured so that the transmitted light of the second polarizing plate reaching the image display mirror is prevented from being transmitted through the first polarizing plate.

Claims

1. A vehicle, comprising:

an image display mirror including a first polarizing plate, a half mirror, and an image display apparatus in the stated order from a viewer side; and

a second polarizing plate,

wherein;

the image display mirror is arranged so as to be viewable by a driver of the vehicle;

the half mirror is configured to be oriented in different directions between when an image is displayed on the image display apparatus and when the image is not displayed thereon;

the second polarizing plate is arranged so that light transmitted through the second polarizing plate reaches a first polarizing plate side of the image display mirror when the image is displayed on the image display apparatus;

the vehicle is configured so that the transmitted light of the second polarizing plate reaching the image display mirror is prevented from being transmitted through the first polarizing plate;

the vehicle comprises a ceiling that transmits light; and

the second polarizing plate is arranged on the ceiling.

2. The vehicle according to claim 1, wherein the half mirror is configured to have, when the image is not displayed, such an arrangement and an angle that the driver is capable of observing a rear with a reflected image, and to be oriented, when the image is displayed, in a direction different from that when the image is not displayed.

3. The vehicle according to claim 1, wherein a position of the first polarizing plate is movable relative to a position of the image display apparatus.

4. The vehicle according to claim 1, wherein a position of the half mirror is movable relative to a position of the image display apparatus.

5. The vehicle according to claim 1, wherein the first polarizing plate and the second polarizing plate are circularly polarizing plates.
