Abstract
The present disclosure relates to an organic light-emitting diode which can operate at a low voltage with high efficiency and exhibits the effect of having an alleviated luminance reduction rate in a low dynamic range. More particularly, the organic light-emitting diode comprises: a first electrode; a second electrode facing the first electrode; and a light-emitting layer and a charge balance control layer arranged sequentially between the first and the second electrode, wherein the light-emitting layer includes at least one of amine derivative compounds represented by the following Chemical Formula A and the charge balance control layer includes at least one of anthracene derivative compounds represented by the following Chemical Formula B or C. The structures of Chemical Formulas A, B, and C are as defined in the specification.
