An apparatus for proving a dimmable reflection and having a layered structure comprises a curved reflective layer, a curved cover glass layer, and at least one liquid crystal film positioned between the curved reflective layer and the curved cover glass layer. Each of the at least one liquid crystal film may comprise a first substrate layer, a first conductive layer, a first alignment layer, a guest host liquid crystal layer, a second alignment layer, a second conductive layer, and a second substrate layer and may be operable in (1) a vertical state, in which liquid crystal molecules are oriented in a direction perpendicular to a plane, associated with a first reflectivity rate and (2) a planar state, in which the liquid crystal molecules are oriented in a direction parallel to the plane, associated with a second overall reflectivity rate lower than the first reflectivity rate.
