Abstract
An optical device that includes a light guide plate, a first deflection means, arranged on at least one of a first surface or a second surface of the light guide plate, that deflects light incident on the light guide plate to cause the light incident on the light guide plate to be totally reflected inside the light guide plate, and a second deflection means, arranged on at least one of the first surface or the second surface of the light guide plate, that deflects the light propagated inside the light guide plate by total reflection to cause the light propagated inside the light guide plate by total reflection to be emitted from the light guide plate. The light guide plate further includes a substrate including a first surface and a second surface facing the first surface, a first planarizing film, formed on the first surface of the substrate, containing an organic material, and a second planarizing film, formed on the second surface of the substrate, containing an organic material. The substrate 500 can contain a resin material.
