Abstract: Discussed is an organic light emitting display device for reducing a color defect or a color difference which occurs in the front or side of the organic light emitting display device. The organic light emitting display device can include a first electrode, a second electrode and an organic layer between the first electrode and the second electrode, the organic layer including at least one emission part. The organic layer is configured for a peak wavelength of an electroluminescence (EL) spectrum of the organic light emitting display device emitted from the at least one emission part to have a range from 10 nm less a predetermined peak wavelength to 10 nm more than the predetermined peak wavelength.

Abstract: Disclosed is an organic light emitting device comprising an anode; a cathode; and a plurality of stacks formed between the anode and the cathode. The plurality of stacks respectively emit their respective light of colors different from one another, wherein the plurality of stacks include a stack emitting blue light and a stack emitting mixed light of blue light and yellow-green to red light. Because the organic light emitting device includes a stack emitting blue light and a stack emitting mixed light of yellow-green to red light and blue light, blue light having a relatively low efficiency may be emitted from the two stacks, whereby overall light emitting efficiency is improved.

Abstract: Provided is an organic light emitting device. The organic light emitting device includes a plurality of light emitting units laminated between a first electrode and a second electrode and each including an organic emitting layer, and a charge generation layer between the light emitting units. Further, the charge generation layer includes an N-type charge generation layer disposed to be in direct contact with an organic emitting layer of the adjacent light emitting unit and HOMO levels of the N-type charge generation layer and the organic emitting layer are regulated. Thus, a color change rate based on a viewing angle can be improved, and efficiency and a lifetime of the organic light emitting device can be improved.
