Disclosed are layered films having a combination of piezoelectric layers that change dimension with applied voltage and non-piezoelectric layers. The layered structures can form a wide range of electrically switchable optical films. These films have applications in displays, polarizers, optical compensators, aesthetic films, and "hot" and "cold" mirrors that selectively reflect only certain wavelengths. Also disclosed are monochromatic and multicolor displays using these films.
