Abstract

Interference of light is prevented from occurring in a rear-view mirror incorporating a light-emitting display device where a dark color mask member is arranged behind a mirror element. A mirror element is formed by forming a semi-transmissive reflective film on one surface of a transparent substrate. On a back surface of the mirror element, a dark color mask member is arranged. An opening a is formed in the dark color mask member Behind the mirror element, a light-emitting display device is arranged facing the opening. A protrusion forming a spacer is formed on the entire peripheral edge of a front surface of the dark color mask member. The spacer provides a clearance gap between the semi-transmissive reflective film and the dark color mask member.
