Abstract

The vehicle mirror includes a high-Re retardation film and a reflective layer. The high-Re retardation film has a front retardation of 5,000 nm or more, and the reflective layer is a reflective layer that is reflective in an unpolarized manner, such as a reflective metal layer. The vehicle mirror may be a vehicle mirror further including an image display device, wherein the high-Re retardation film, the reflective layer, and the image display device are disposed in this order, and the reflective layer is transflective.

Claims

1. A vehicle mirror comprising:

a high-Re retardation film; and

a reflective layer, the high-Re retardation film and the reflective layer being disposed in this order from a viewer side,

wherein the high-Re retardation film has a front retardation of 5,000 nm or more, and

the reflective layer is reflective in an unpolarized manner.

2. The vehicle mirror according to claim 1, wherein the reflective layer is a reflective metal layer or a dielectric multilayer film.

3. The vehicle mirror according to claim 2, wherein the reflective metal layer includes aluminum or silver.

4. The vehicle mirror according to claim 2, wherein the reflective metal layer includes aluminum.

5. The vehicle mirror according to claim 2, wherein the reflective metal layer is a vapor-deposited layer.

6. The vehicle mirror according to claim 3, wherein the reflective metal layer is a vapor-deposited layer.

7. The vehicle mirror according to claim 4, wherein the reflective metal layer is a vapor-deposited layer.

8. The vehicle mirror according to claim 1, wherein the front retardation is 7,000 nm or more.

9. The vehicle mirror according to claim 1, wherein the high-Re retardation film is a polyester film.
