摘要：
A film stack includes a plurality of first films and a plurality of second films alternately stacked. At least one second film of the plurality of second films includes a solid crystal including crystal molecules aligned in a predetermined alignment direction. At least one first film of the plurality of first films includes an alignment structure configured to at least partially align the crystal molecules of the solid crystal in the predetermined alignment direction.
