Abstract: An organic electroluminescent device includes a plurality of main pixels. Each of the main pixels includes red, green, and blue sub-pixels. Each of the sub-pixels includes a first electrode, a second electrode opposite to the first electrode, and an organic light emitting layer between the first and second electrode. The organic light emitting layer of each of the sub-pixels includes a blue light emitting layer and a green light emitting layer. Optical microresonator distances of the red, green, and blue sub-pixels are different from each other.
