  • Publication number: 20240260296
    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 ? to ? of the first thickness.
