Vehicle mirror with image display function

Abstract

A vehicle mirror with an image display function includes a half mirror which includes a high-Re retardation film and a reflection layer and an image display device on the half mirror, in which the high-Re retardation film, the reflection layer, and the image display device are disposed in this order, the high-Re retardation film has a front phase difference of 5000 nm or greater, and the reflection layer is a linear polarization reflection layer.

What is claimed is: 
     
         1 . A vehicle mirror with an image display function comprising:
 a half mirror which includes a high-Re retardation film and a reflection layer; and   an image display device on the half mirror,   wherein the high-Re retardation film, the reflection layer, and the image display device are disposed in this order,   the high-Re retardation film has a front phase difference of 5000 nm or greater, and   the reflection layer is a linear polarization reflection layer.   
     
     
         2 . The vehicle mirror with an image display function according to  claim 1 ,
 wherein the front phase difference is 7000 nm or greater.   
     
     
         3 . The vehicle mirror with an image display function according to  claim 1 ,
 wherein the linear polarization reflection layer is a linear polarization reflection plate having a multi-layer structure, a polarizer including a laminate of thin films having different types of birefringence, a wire grid polarizer, a polarizing prism, or a scattering anisotropic polarizing plate.   
     
     
         4 . The vehicle mirror with an image display function according to  claim 1 ,
 wherein the linear polarization reflection layer is a polarizer including a laminate of thin films having different types of birefringence.   
     
     
         5 . The vehicle mirror with an image display function according to  claim 1 ,
 wherein the half mirror includes a front surface plate, and   the front surface plate, the high-Re retardation film, and the reflection layer are provided in this order.   
     
     
         6 . The vehicle mirror with an image display function according to  claim 1 ,
 wherein the half mirror includes a front surface plate,   the front surface plate is a laminated glass including two glass plates and an interlayer between the two glass plates, and   the interlayer includes the high-Re retardation film.   
     
     
         7 . The vehicle mirror with an image display function according to  claim 1 ,
 wherein the half mirror is a laminated glass including two glass plates and an interlayer between the two glass plates, and   the interlayer includes the high-Re retardation film and the reflection layer.
