Abstract

To provide a mirror with a monitor for a vehicle that allows display light to pass through a region of a mirror surface thereof to be visually recognized by a viewer, in which the viewability of the display is improved while suppressing the cost increase. A region of a mirror element that transmits display light is formed of a wire grid having a polarization direction that agrees with the polarization direction of the display light. A region of the mirror element adjacent to the wire grid is formed of a reflective film formed of a reflective metal film or a dielectric multilayer film. The grid of the wire grid is formed of Al thin lines, for example. The reflective film is formed of a Cr half mirror, for example. A dark color mask is disposed on the back surface of the Cr half mirror.

Claims

1. A mirror with a monitor for a vehicle that allows linearly polarized display light emitted from a light emitting display device to pass through a region of the mirror surface from a back side of a mirror surface thereof to be visually recognized by a viewer,

wherein the region of the mirror surface through which the display light passes is formed of a reflective polarizing film having a polarization direction that agrees with the polarization direction of the display light, and

a region of the mirror surface adjacent to the reflective polarizing film is formed of a reflective film formed of a reflective metal film or a dielectric multilayer film.

2. The mirror with a monitor for a vehicle according to claim 1, wherein the region of the mirror surface adjacent to the reflective polarizing film is formed of a half mirror formed of a reflective metal film or a dielectric multilayer film, and

a dark color mask is disposed on a back surface of the half mirror.

3. The mirror with a monitor for a vehicle according to claim 1, wherein the reflective polarizing film is formed of a wire grid.

4. The mirror with a monitor for a vehicle according to claim 2, wherein the reflective polarizing film is formed of a wire grid.

5. The mirror with a monitor for a vehicle according to claim 3, wherein a grid of the wire grid is formed of Al thin lines, and the reflective film is formed of a Cr half mirror.

6. The mirror with a monitor for a vehicle according to claim 4, wherein a grid of the wire grid is formed of Al thin lines, and the reflective film is formed of a Cr half mirror.

7. The mirror with a monitor for a vehicle according to claim 1, wherein the reflective film is disposed on a back surface of a transparent substrate, and

the reflective polarizing film is disposed on a region of the back surface of the transparent substrate where the reflective film is not disposed.

8. The mirror with a monitor for a vehicle according to claim 2, wherein the reflective film is disposed on a back surface of a transparent substrate, and

the reflective polarizing film is disposed on a region of the back surface of the transparent substrate where the reflective film is not disposed.

9. The mirror with a monitor for a vehicle according to claim 3, wherein the reflective film is disposed on a back surface of a transparent substrate, and

the reflective polarizing film is disposed on a region of the back surface of the transparent substrate where the reflective film is not disposed.

10. The mirror with a monitor for a vehicle according to claim 4, wherein the reflective film is disposed on a back surface of a transparent substrate, and

the reflective polarizing film is disposed on a region of the back surface of the transparent substrate where the reflective film is not disposed.

11. The mirror with a monitor for a vehicle according to claim 5, wherein the reflective film is disposed on a back surface of a transparent substrate, and

the reflective polarizing film is disposed on a region of the back surface of the transparent substrate where the reflective film is not disposed.

12. The mirror with a monitor for a vehicle according to claim 6, wherein the reflective film is disposed on a back surface of a transparent substrate, and

the reflective polarizing film is disposed on a region of the back surface of the transparent substrate where the reflective film is not disposed.

13. The mirror with a monitor for a vehicle according to claim 7, wherein the reflective polarizing film is attached to the back surface of the transparent substrate or a display surface of the light emitting display device.

14. The mirror with a monitor for a vehicle according to claim 8, wherein the reflective polarizing film is attached to the back surface of the transparent substrate or a display surface of the light emitting display device.

15. The mirror with a monitor for a vehicle according to claim 9, wherein the reflective polarizing film is attached to the back surface of the transparent substrate or a display surface of the light emitting display device.

16. The mirror with a monitor for a vehicle according to claim 10, wherein the reflective polarizing film is attached to the back surface of the transparent substrate or a display surface of the light emitting display device.

17. The mirror with a monitor for a vehicle according to claim 11, wherein the reflective polarizing film is attached to the back surface of the transparent substrate or a display surface of the light emitting display device.

18. The mirror with a monitor for a vehicle according to claim 12, wherein the reflective polarizing film is attached to the back surface of the transparent substrate or a display surface of the light emitting display device.
