An electro-optic element includes a first substrate defining first and second surfaces. The second surface includes a first electrically conductive layer. A second substrate defines third and fourth surfaces. The third surface includes a second electrically conductive layer. A primary seal is disposed between the first and second substrates. The seal and the first and second substrates define a cavity therebetween. An electro-optic material is disposed in the cavity. The electro-optic material being variably transmissive such that the electro-optic element is operable between substantially clear and darkened states. A transflective film includes a liquid crystal material. The transflective film has a thickness of from about 6 μm to about 24 μm. An adhesion layer is positioned between the transflective film and the second substrate. An alignment layer is positioned between the transflective film and the adhesion layer.
