AI Technical Summary

Benefits of technology

The solution effectively eliminates brightness and color unevenness in mirror-reflected images, providing a clear and consistent view of external scenery when used as an inner vehicle mirror.

Problems solved by technology

The visible light transmittance of a half mirror is generally about 30% to 70%, and a configuration provided with a half mirror has a potential problem in that images become darker than in a configuration having no half mirror.
However, in a case where the inventors have formed a mirror with an image display function using a reflective polarizing plate and used the mirror in a vehicle, brightness unevenness or color unevenness (iridescence) has been caused in a mirror-reflected image.

[0194][Synthesis of Raw Material Polyester]

[0195](Raw Material Polyester 1)

[0196]As shown below, terephthalic acid and ethylene glycol were directly reacted with each other and water was distilled away. After esterification, using a direct esterification method including polycondensation under reduced pressure, raw material polyester 1 (Sb catalyst-based PET) was obtained by a continuous polymerization apparatus.

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.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a Continuation of US application No. U.S. Ser. No. 15 / 837,441 filed on Dec. 11, 2017, which claims priority under 35 U.S.C. § 119(a) to PCT International Application No. PCT / JP2016 / 065868, filed on May 30, 2016, and Japanese Patent Application No. 2015-126431, filed on Jun. 24, 2015. Each of the above application(s) is hereby expressly incorporated by reference, in its entirety, into the present application.BACKGROUND OF THE INVENTION1. Field of the Invention[0002]The present invention relates to a vehicle mirror with an image display function.2. Description of the Related Art[0003]For example, in JP2014-201146A, a vehicle mirror with an image display function is described which is capable of displaying images such as images taken by a car-mounted camera on the vehicle mirror. In the vehicle mirror with an image display function disclosed in JP2014-201146A, a liquid crystal display device is provided inside a housing o...
