摘要： An organic light emitting diode and an organic light emitting display device using the same are provided to facilitate movement of electrons or holes by gradually increasing or decreasing an energy barrier by forming at least one of a hole injecting layer and an electron injecting layer in a multi-layer structure. An organic light emitting diode(40) includes a hole injecting layer(420), a light emitting layer(430), an electron injecting layer(440), and a second electrode(450). The hole injecting layer is formed on a first electrode(410). The light emitting layer is formed on the hole injecting layer. The electron injecting layer is formed on the light emitting layer. The second electrode is formed on the electron injecting layer. A difference between absolute values of work functions of the first and second electrodes is 0.5eV or less. At least one of the hole injecting layer and the electron injecting layer is formed in a multi-layered structure. The hole injecting layer is a HOME(Highest Occupied Molecular Orbital) energy level. The electron injecting layer is an LUMO(Lowest Unoccupied Molecular Orbital).
