    • There is provided a reflection type optical control device in which light use efficiency is improved. An optical control device (8) has a plurality of pixels (10) two-dimensionally arranged on a substrate (30). A first reflection layer (32) is formed on the substrate (30). A light modulation film (34) is arranged on the first reflection layer (32). The light modulation film (34) is formed by an electro-optical material such as PLZT whose refraction factor is changed according to the electric field applied. A transparent electrode (36) is arranged on the upper surface of the light modulation film (34). A second reflection layer (40) is formed on the upper surface of the transparent electrode (36). The second reflection layer (40) is includes a dielectric multi-layer film formed by a first dielectric film (42) and a second dielectric film (44) having different refraction factors layered alternately. The first reflection layer (32), the light modulation film (34), and the second reflection layer (40) constitute a resonator. The transparent electrode (36) and the first reflection layer (32) constitute an electrode pair for controlling the reflection ratio of the optical control device (8) by the electric field applied to the light modulation film (34).
