An interferometric modulator that can be suitably used in a reflective display device is provided. A transparent substrate (refractive index: n 0 ) 12, an optical thin film (complex refractive index: N 1 = n 1 −i · k 1 ) 13 provided on the transparent substrate 12, and the optical thin film 13 are opposed to each other. And an absorber layer (complex refractive index: N s = n s −i · k s ) 14 in which the gap distance from the optical thin film 13 is variably arranged, and n 1 > n 0 , k 1 ≈ 0 and the relationship of n s > n 0 is satisfied.
