ABSTRACT:
A structure includes a substrate and a light modulating film formed on top of the substrate. The light modulating film is made of polycrystalline PLZT containing Pb, Zr, Ti, and La as constituent elements. The film has a La concentration in the range of 5 at % to 30 at %. The relative dielectric constant at a frequency of 1 MHz is higher than or equal to 1200.
