Organic light-emitting diode, organic light-emitting display device including the same, and method of controlling dual emission of organic light-emitting diode

摘要

An organic light-emitting diode, an organic light-emitting display device including the same, and a method of controlling dual emission of the organic light-emitting diode. The organic light-emitting diode (OLED) includes: a first electrode (BE) and a second electrode (TE) facing each other; a common electrode (CE) interposed between the first electrode (BE) and the second electrode (TE); a first organic layer (20a) interposed between the first electrode (BE) and the common electrode (CE); and a second organic layer (20b) that is interposed between the second electrode (TE) and the common electrode (BE) and is reverse-symmetric to the first organic layer (20a) with respect to the common electrode (CE).
