According to an embodiment, an electrically switchable mirror includes: a first electrically switchable layer of cholesteric liquid crystal material, the first electrically switchable layer having a first state in which right-handed circularly polarized light incident thereon is reflected and left-handed circularly polarized light incident thereon is transmitted and a second state wherein right-handed and left-handed circularly polarized light incident thereon are transmitted; a second electrically switchable layer of cholesteric liquid crystal material, the second electrically switchable layer having a first state in which left-handed circularly polarized light incident thereon is reflected and right-handed circularly polarized light incident thereon is transmitted and a second state wherein right-handed and left-handed circularly polarized light incident thereon are transmitted; and a first electrically switchable wave plate disposed between the first and second electrically switchable layers.
