An organic EL display equipped with an organic EL device with an organic material sandwiched by at least two electrodes, including: a light emitting layer which emits light; a front reflecting portion arranged on the side of a viewer with respect to the light emitting layer; and a rear reflecting portion arranged on the side opposite to the viewer with respect to the light emitting layer, wherein the optical film thickness of the organic material, intensity reflectance R.sub.1 at the front reflecting portion and intensity reflectance R.sub.2 at the front reflecting portion are adjusted so that the external light intensity reflectance of the display viewed from the viewer is 10% or less by an optical interference effect.
