Abstract
To provide a vehicle rear-view mirror equipped with a display device, configured so that: a warning indication is easy to see from the driver and is hard to see from following vehicles and vehicles on the adjacent lanes; and when no warning is indicated, no discontinuities occur in the rear-area image reflected in the mirror and the warning symbol is unnoticeable. A mirror element 18 is configured by forming a semi-transmissive reflective film 24 or 56 formed of a dielectric multilayer film on the back or front surface of a transparent glass substrate 22. A dark color mask member 26 is arranged on the back surface of the mirror element 18. An opening 26a is formed on the mask member 26. A light-orienting tube 28 is arranged in such a manner that it protrudes in the backward direction of the mask member 26 so as to surround the opening 26a. The tube axis 28a of the light-orienting tube 28 is inclined in the direction toward the driver's viewpoint. An indication mask 32, a light diffusion plate 34 and an LED 36 are arranged as an indication light-emitting portion 30 by depositing them in this order on a rear end-side opening 28b of the light-orienting tube 28.
