Abstract: Provided is an organic light emitting display device including at least two organic light emitting elements disposed adjacent to each other, respectively including an anode, an organic light emitting unit, and a cathode, and sharing at least one common layer in the organic light emitting unit. The at least one common layer includes a characteristic degradation area that reduces or minimizes an amount of leakage current generated between the at least two organic light emitting elements.

Abstract: A display device includes a first active area in which a plurality of first pixels are disposed and which has a first resolution, a second active area in which a plurality of second pixels are disposed and which has a second resolution lower than the first resolution, and multiple light-emitting elements, wherein each of the multiple light-emitting elements includes an electron-blocking layer and a hole-blocking layer, wherein the number of moles of a dopant in at least one of the electron-blocking layer or the hole-blocking layer located in the second active area is greater than the number of moles of a dopant in at least one of the electron-blocking layer or the hole-blocking layer located in the first active area. Accordingly, the difference in luminance between the first active area and the second active area may be reduced.
