Abstract:
1. A method of fabricating an organic light-emitting diode, comprising: forming an anode on the entire surface of a substrate on which a red pixel area, a green pixel area, and a blue pixel area are defined; forming a first hole transporting layer on the anode and corresponding to the red pixel area, the green pixel area, and the blue pixel area; forming a second hole transporting layer on the first hole transporting layer and corresponding to the red pixel area and the green pixel area, the second hole transporting layer having a uniform thickness; forming an electron blocking layer on the second hole transporting layer in the red and green pixel areas and the first hole transporting layer in the blue pixel area; forming a red organic light-emitting pattern on electron blocking layer and corresponding to the red pixel area; forming a green organic light-emitting pattern on the red organic light-emitting pattern and the electron blocking layer in the green pixel area; forming a blue organic light-emitting pattern on the green organic light-emitting pattern in the red and green pixel areas and the electron blocking layer in the blue pixel area; forming an electron transporting layer on the blue organic light-emitting pattern; and forming a cathode on the electron transporting layer.
