Abstract: Discussed is an organic light emitting device including a substrate. The substrate can include red, green and blue pixel regions, and an organic light emitting diode including an anode, a cathode over the anode and an organic emitting layer between the anode and the cathode and corresponding to the red, green and blue pixel regions. The organic emitting layer includes a first emitting part including a red emitting material layer, a second emitting part including a green emitting material layer and positioned between the first emitting part and the cathode and a third emitting part including a blue emitting material layer and positioned between the second emitting part and the cathode. The anode in the blue pixel region has a first thickness, and the anode in the green pixel region has a second thickness being approximately ⅖ to ⅔ of the first thickness.

Abstract: An OLED includes a plurality of emitting parts among which a first emitting part includes an electron transport layer and a second emitting part includes a hole transport layer spaced apart from a second emitting material layer. At least one of the hole transport layer and the electron transport layer may include a high refractive material, so that, an optical location of the OLED may be controlled. The OLED with driving at low power consumption, improved blue light luminous efficiency and white light luminance and a stable viewing angle may be implemented.
