Abstract: Provided is a display device, including two light-emitting elements having different turn-on voltages. Each of the light-emitting elements includes a patterned electrode, a common layer, a patterned light-emitting layer, and a common electrode. The light-emitting element with the lower turn-on voltage among the two light-emitting elements includes a functional layer which suppresses a hole from being leaked from the light-emitting layer with the higher turn-on voltage through the common layer when the light-emitting element with the higher turn-on voltage among the two light-emitting elements is driven at a low gray scale to move into the patterned light-emitting layer of the light-emitting element with the lower turn-on voltage. Therefore, the light emission of an undesired pixel due to the leakage current is reduced, thereby improving the display quality.

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.
