摘要：
An optical filter includes a first substrate, a second substrate opposed to the first substrate, a first optical film provided on a surface of the first substrate facing the second substrate, a second optical film provided on the second substrate and opposed to the first optical film via a gap, a first electrode provided on the surface of the first substrate facing the second substrate, and a second electrode provided on the second substrate and opposed to the first electrode, wherein a first charged body film with charge is formed on top of the first optical film, a second charged body film with charge is formed on top of the second optical film, and the first charged body film and the second charged body film are charged with the same polarity and opposed.
