Abstract

A mirror with display device includes a transparent planar material; and a display device. The transparent planar material has a metallic thin film. A light-shielding part is formed in the transparent planar material so that the transparent planar material has a translucent part. A display part of the display device for displaying an image is bonded to the translucent part via an adhesive layer.

Claims

1. A mirror with a display device comprising:

a transparent planar material; and

the display device,

wherein the transparent planar material has a metallic thin film on an entire surface of at least one of surfaces of the transparent planar material, and a light-shielding part is formed in the transparent planar material so that the transparent planar material has a translucent part,

wherein a display part of the display device for displaying an image is bonded to the translucent part via an adhesive layer, and

wherein the light-shielding part is formed between the metallic thin film and the display device.

2. The mirror with display device according to claim 1, wherein the metallic thin film is formed on one surface of the transparent planar material, and the light-shielding part is formed on another surface of the transparent planar material.
