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.

Abstract: A display device can include a substrate having a display area including a plurality of light emitting diodes, a first non-display area, and a bending area disposed between the first non-display area and the display area; a first inorganic encapsulation layer on the plurality of light emitting diodes; and a data driver in the first non-display area, in which the substrate is configured to be bent at the bending area for locating a portion of the first non-display area that includes the data driver under or behind a portion of the display area, and the first inorganic encapsulation layer includes a first region configured to overlap with the data driver and a second region that does not overlap with the data driver, the first region of the first inorganic encapsulation layer having a higher refractive index than the second region of the first inorganic encapsulation layer.

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.
