As another example, the amine-based compound represented by Formula 1 may be selected from the following compounds 1 to 48, but is not limited thereto:

In the organic light emitting device, when hole injection into the emission layer is less than that of electron injection, excitons generated in the emission layer may collide with excess electrons. Accordingly, exciton-polaron quenching occurs in the emission layer, and the excitons in the emission layer are dissociated, thereby reducing the efficiency of the organic light emitting diode.

In addition, since the difference between the hole injection amount and the electron injection amount becomes larger under a high current, a phenomenon in which the efficiency decrease becomes more pronounced as the current increases, that is, a roll-off phenomenon occurs.

The amine-based compound represented by Formula 1 facilitates hole injection from the hole transport region to the emission layer, thereby increasing the charge balance in the emission layer. Accordingly, the organic light-emitting device including the amine-based compound represented by Formula 1 may have increased efficiency and reduced roll-off.

In addition, since the amine-based compound represented by Formula 1 has high thermal stability, an organic light-emitting device including the same may have little change in efficiency according to temperature.

The auxiliary layer may have a thickness of about 10 Å to about 800 Å, for example, about 50 Å to about 500 Å. When the thickness of the auxiliary layer satisfies the above-mentioned range, a satisfactory level of hole transport characteristics may be obtained without a substantial increase in driving voltage.

A vacuum deposition method, a spin coating method, a casting method, a LB method (Langmuir-Blodgett), an inkjet printing method, a laser printing method, or a laser induced thermal imaging (LITI) method on the upper portion of the first electrode 110 or on the hole transport region ) to form the light emitting layer using various methods such as When the light emitting layer is formed by vacuum deposition and spin coating, the deposition conditions and coating conditions of the light emitting layer refer to the deposition conditions and coating conditions of the hole injection layer.

When the organic light emitting device 10 is a full-color organic light emitting device, it may be patterned into a red light emitting layer, a green light emitting layer, and a blue light emitting layer for each light emitting layer and each sub-pixel. Alternatively, the light emitting layer has a structure in which a red light emitting layer, a green light emitting layer, and a blue light emitting layer are stacked, or has a structure in which a red light emitting material, a green light emitting material and a blue light emitting material are mixed without layer distinction, so that white light can be emitted. Alternatively, the light emitting layer may be a white light emitting layer, and may further include a color converting layer for converting the white light into light of a desired color or a color filter.
