Claim:
1. An organic light emitting diode in each of red, green and blue sub pixels, comprising: a first electrode and a second electrode; an organic light emitting layer between the first electrode and the second electrode; and an auxiliary light emitting layer between the first electrode and the organic light emitting layer or between the organic light emitting layer and the second electrode, wherein a difference between a main peak wavelength of light emitted from the organic light emitting layer itself and a main peak wavelength of light out-coupling between the first and second electrodes is within a range of −14 nm to −2 nm, wherein the main peak wavelength of light out-coupling between the first and second electrodes has a larger value than the main peak wavelength of light emitted from the organic light emitting layer itself in each of the green and blue sub pixels, and wherein a value of a maximum peak at a curve of a color coordinate variation rate (Δu′v′) of the organic light emitting diode is equal to or less than 0.043 within a range of viewing angles of −80 degrees to +80 degrees.
