Transflective film for electro-optic elements

An electro-optic element comprising:

• a first substrate defining first and second surfaces;
• a second substrate defining third and fourth surfaces;
• a primary seal disposed between the first and second substrates, wherein the seal and the first and second substrates define a cavity therebetween;
• an electro-optic material disposed in the cavity, wherein the electro-optic material is variably transmissive;
• and
• a transflective film comprising a liquid crystal material, wherein the transflective film comprises an average roughness of less than about 18 nm and wherein a waviness of the transflective film is less than about 0.38.

An electro-optic element comprising:

• a first substrate defining first and second surfaces, wherein the second surface comprises a first electrically conductive layer;
• a second substrate defining third and fourth surfaces, wherein the third surface comprises a second electrically conductive layer;
• a primary seal disposed between the first and second substrates, wherein the seal and the first and second substrates define a cavity therebetween;
• an electro-optic material 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 comprising a liquid crystal material, wherein the transflective film has a thickness of from about 6 μm to about 24 μm and a waviness of less than about 0.9;
• an adhesion layer positioned between the transflective film and the second substrate;
• and
• an alignment layer positioned between the transflective film and the adhesion layer.
