The present invention has the object of suppressing variations of luminance and chromaticity among a plurality of organic EL elements. An illumination device includes: a plurality of organic EL elements; an operation unit that receives, for each organic EL element, chromaticity information that indicates chromaticity of the relevant organic EL element and luminance information that indicates the luminance of the relevant organic EL element; and a supply unit that, for each of the organic EL elements, supplies to an organic EL element a drive signal having amplitude that accords with the chromaticity indicated by the chromaticity information for that organic EL element for, within a unit time interval, a time interval that accords with luminance indicated by the luminance information for that organic EL element.
