  • Patent number: 11522139
    Abstract: Disclosed herein are an organic light emitting diode including: at least two light emitting stacks interposed between an anode and a cathode and including at least one light emitting material layer; and a charge generation layer interposed between the light emitting stacks. The charge generation layer includes an N-type charge generation layer and a P-type charge generation layer, wherein the N-type charge generation layer and the P-type charge generation layer are stacked in such direction for the N-type charge generation layer to face the anode and for the P-type charge generation layer to face the cathode. The N-type charge generation layer includes a compound represented by Formula 1. The P-type charge generation layer includes any one selected from the group consisting of a compound represented by Formula 2, a compound represented by Formula 3, and a combination thereof.
