摘要： In an organic light emitting display device, a plurality of pixel regions are formed two-dimensionally on a transparent substrate, wherein each pixel region includes the multilayered structure which is formed by sequentially stacking a lower transparent electrode, an organic light emitting layer (including at least one organic material layer) and an upper reflection electrode from the transparent substrate side. In such a constitution, at least one concavity which forms a recessed surface with respect to the transparent substrate is formed in the multilayered structure of each pixel region, thus enlarging the effective area of a light emitting portion so as to provide an image display of high brightness with a low current. The concavities are, for example, formed by a plurality of projecting portions on the transparent substrates and by covering the projecting portions with the multilayered structure.
