Claims12
An organic light emitting diode, comprising:
- a first electrode;
- a second electrode facing the first electrode;
- a first emitting material layer positioned between the first and second electrodes;
- and
- a hole injection layer positioned between the first electrode and the first emitting material layer and including a hole injection material;
- a second emitting material layer between the first emitting material layer and the second electrode;
- and
- a first p-type charge generation layer including a first p-type charge generation material and positioned between the first and second emitting material layers,
- wherein each of the hole injection material and the first p-type charge generation material is an organic compound in Formula 1-4:
- wherein each of R1 and R2 is independently selected from the group consisting of hydrogen, deuterium, halogen and cyano,
- wherein each of R3 to R6 is independently selected from the group consisting of halogen, cyano, malononitrile, C1 to C10 haloalkyl group and C1 to C10 haloalkoxy group, and at least one of R3 and R4 and at least one of R5 and R6 are malononitrile,
- wherein each of X1 to X3 and each of Y1 to Y3 are independently selected from the group consisting of H, C1 to C10 alkyl group, halogen, cyano, malononitrile, C1 to C10 haloalkyl group, and C1 to C10 haloalkoxy group, and satisfy at least one selected from i) X1 and Y1 are different and ii) X2 is different from Y2 and Y3, or X3 is different from Y2 and Y3, and
- wherein a weight % of the first p-type charge generation material in the first p-type charge generation layer is greater than a weight % of the hole injection material in the hole injection layer.
