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.

An organic light emitting display device is discussed. The organic light emitting display device can include at least two or more light emitting parts each including a light emitting layer and an electron transport layer; and a charge generation layer between the two or more light emitting parts and including an N-type charge generation layer, wherein the electron transport layer includes an electron transport compound including a functional group with high electron mobility, and the N-type charge generation layer includes a charge generation compound including a functional group for matching the energy level of the electron transport compound.

Organic light emitting display device

An organic light-emitting device includes a first electrode and a second electrode, a first organic emission layer disposed between the first electrode and the second electrode and comprising a first dopant, and a second organic emission layer disposed between the first electrode and the second electrode and comprising a second dopant. The maximum luminescence wavelength of the first dopant may be larger than the maximum luminescence wavelength of the second dopant. The difference between the maximum luminescence wavelength of the first dopant and the maximum luminescence wavelength of the second dopant is 10 nm or less.
