The present invention discloses organic electroluminescent display device and a method for fabricating the same, which includes: a first hole transporting layer formed in the first, second, and third pixel regions; a second hole transporting layer formed on a portion of the first hole transporting layer in the second and third pixel regions; a third hole transporting layer formed on a portion of the second hole transporting layer in the third pixel region. Light emitting layers are formed on each of the first, second, and third hole transporting layers. The thickness of the second hole transporting layer is approximately one-third (1/3) to two-thirds (2/3) of an optical wavelength difference between the first and second pixel regions, and the thickness of the third hole transporting layer is approximately one-third (1/3) to two-thirds (2/3) of an optical wavelength difference between the second and third pixel regions.
