An electrochromic rearview mirror element for a motor vehicle comprises a first substantially transparent front substrate having a first and a second surface (and with a substantially transparent conductive electrode on its second surface) and a rear substrate having a third and a fourth surface. The rear substrate is positioned in spaced-apart relationship with the front substrate and with its third surface opposing the second surface of the front substrate. A mirror reflector is disposed on the third surface and a seal is positioned toward a peripheral edge of the substrates forming a cavity therebetween. An electrochromic medium is disposed in the cavity. The mirror reflector preferably comprises a metal layer that reflects at least about 70% of visible light. A display device can be disposed behind the rear substrate. The display device preferably exhibits, when electrically powered, a display luminance of at least about 30 foot lamberts as measured with the display device placed behind, and emitting light through, the electrochromic medium and with the electrochromic medium in its bleached state.
