Abstract

PROBLEM TO BE SOLVED: To obtain excellent visibility by letting a boundary line between the screen of a monitor device and each of the other surfaces be obscure because the inner surface of a mirror housing is roughly identical in color to the screen of the monitor device. SOLUTION: A reflecting film 4 composed of a multi-layer film is provided for the back surface of a mirror substrate 3, a monitor device is disposed to the back surface of the reflecting film 4, and the inner surface of a mirror housing is formed into the color of a screen when the monitor device is out of operation. As a result, since the inner surface of the mirror housing is roughly identical in color to the screen 70, the boundary line between the screen 70 of the monitor device 7 and each of the other mirror 2 surfaces become obscure, so that excellent visibility can thereby be obtained.

The vehicle mirror with a built-in monitor device according to the present invention in this embodiment has the above-described configuration. When the monitor device 7 is turned on, a mirror device 2 (not shown) is used in the mirror 2. Information on the surroundings of the caught vehicle is displayed as a camera image on the screen 70 of the monitor device 7.
It is projected to. That is, since the mirror 2 is a half mirror, the camera image on the screen 70 of the monitor device 7 is
The light can be visually recognized through the mirror 2 through a semi-transmission. At this time, a rear view image is projected on the mirror 2 surface other than the screen 70 of the monitor device 7. That is, since the mirror 2 is a half mirror, a rear view image is projected with a predetermined reflectance. When the monitor device 7 is in the off state, a rear view image is projected on the entire surface of the mirror 2. At this time, since the colored surface 5 on the inner surface of the mirror housing 1 and the screen 70 of the monitor device 7 have substantially the same color (black), the boundary line 8 between the screen 70 of the monitor device 7 and the other mirror 2 surface (FIG. (Indicated by the middle broken line)) becomes unclear, and good visibility is obtained. Note that the color of the colored coating film 5 and the color of the screen 70 in the off state of the monitor device 7 are obtained as reflected colors.
