A vehicular rearview assembly, includes a front substrate defining a first surface and a second surface. The front substrate being substantially transparent. The front substrate defines a shaped edge along a periphery of the first surface. A first polarizer is coupled with the second surface. An electro-optic element is coupled to the first polarizer having a first substrate defining a first element surface and a second element surface. A second substrate is spaced away from the first substrate and defines a third element surface and a fourth element surface. An electro-optic material is positioned between the first and second substrates. A second polarizer is coupled to the fourth element surface. A display is configured to emit light having a first polarization into the second polarizer. A reflective layer is positioned between the front substrate and the display is configured to reflect both the first polarization of light and a second polarization of light.
