Organic light emitting device and display device including the same
Abstract:
An organic light emitting device includes: a first electrode; a second electrode that overlaps the first electrode; and an organic layer that is disposed between the first electrode and the second electrode, wherein the organic layer comprises a hole transport region that includes a hole transport material and a p-dopant, and wherein when a doping amount of the p-dopant doped to the hole transport region exceeds 1 wt %, the following Equation 1 is satisfied, while when the doping amount of the p-dopant is 1 wt % or less than 1 wt %, the following Equation 2 is satisfied: HOMO_HTM−LUMO_p-dopant −0.05 eV  [Equation 2] In Equation 1 and Equation 2, HOMO_HTM denotes HOMO energy of the hole transport material and LUMO_p-dopant denotes LUMO energy of the p-dopant.
