Organic light emitting diode and organic light emitting display device including the same

An organic light emitting display device, comprising:

• a substrate,
• a thin film transistor,
• an organic light emitting diode on the thin film transistor,
• wherein the organic light emitting diode includes:
• a first electrode and a second electrode facing each other;
• an emission layer between the first electrode and the second electrode;
• and
• a hole transfer layer between the first electrode and the emission layer, and
• wherein:
• the hole transfer layer includes an organic material and a dipole material,
• the dipole material includes a first component and a second component,
• the first component has a polarity different from that of the second component, the first component and the second component being combined with each other,
• the emission layer includes a red emitting layer, a green emitting layer, and a blue emitting layer, and
• the emission layer further includes an auxiliary layer disposed at a lower end of the blue emitting layer.
