    摘要： An organic light emitting device can include a first electrode and a second electrode, and a red emission layer, a green emission layer and a blue emission layer which are positioned between the first electrode and the second electrode. Each of the red emission layer, the green emission layer and the blue emission layer can be disposed in an entirety of a red sub-pixel area, a green sub-pixel area and a blue sub-pixel area. A distance between the first electrode and the second electrode in at least one of the red sub-pixel area, the green sub-pixel area and the blue sub-pixel area can be a first-order optical distance equal to λ/2n, where λ is a wavelength of light emitted from each of the sub-pixel areas, and n is an average refractive index of a plurality of organic material layers disposed between the first electrode and the second electrode.
