According to the present invention, an optical device includes: a first electro-optical member and a second electro-optical member. The first electro-optical member has two convex portions spaced from each other by a recessed portion and a connecting portion arranged under the recessed portion to connect the two convex portions, the first electro-optical member exhibiting an electro-optical effect. The second electro-optical member has a recessed portion member arranged within the recessed portion, the second electro-optical member exhibiting an electro-optical effect. The permittivity of the first electro-optical member is higher than the permittivity of the second electro-optical member. The refractive index of the first electro-optical member is higher than the refractive index of the second electro-optical member. During application of an electric field, light to be transmitted is applied to the recessed portion member.
