  • Organic light-emitting diode including an interlayer to maintain a hole-electron balance in the emitting layer and display panel including the same
    Patent number: 9755171
    Abstract: An organic light-emitting diode includes: a first electrode layer disposed on a base substrate; a second electrode layer disposed above the first electrode, and opposed to the first electrode; a emitting layer disposed between the first electrode layer and the second electrode layer, and including an inorganic material; a hole transport region disposed between the emitting layer and the first electrode layer; a first electron transport region disposed between the emitting layer and the second electrode layer; a interlayer disposed between the emitting layer and the first electron transport region, and having a lowest unoccupied molecular orbital (LUMO) energy level higher than that of the second electron transport region; and a second electron transport region disposed between the emitting layer and the interlayer, and contacting the emitting layer.
