Beschreibung
Zusammenfassung:	A rearview mirror with a dimming function includes: a transparent cover substrate covering substantially the full screen of the rearview mirror, an absorptive polarization layer disposed below the transparent cover substrate with a substantially uniform size, where when non-polarized ambient light passes through the absorptive polarization layer, the layer absorbs light of a polarization parallel to its absorption axis while transmits light of a polarization perpendicular to its absorption axis, a liquid crystal light-controlling layer disposed below the absorptive polarization layer with a substantially uniform size, and a reflective polarization layer disposed below the liquid crystal light-controlling layer with a substantially uniform size, which reflects the light of a polarization parallel to its reflective axis while transmits the light of a polarization perpendicular to its reflective axis. The rearview mirror can automatically adjust reflective light, while improving the utilization of the display light.
