Abstract
An organic light-emitting device includes a first transistor for applying a data voltage; a second transistor for applying a driving current depending on the data voltage and an initiation voltage to an organic light-emitting diode; a third transistor for generating a threshold voltage; a fourth transistor for applying an initiation voltage, the fourth transistor being connected to the third transistor; a fifth transistor for applying a power voltage; and a condenser provided between a first node connected to the third and fifth transistors and a second node connected to the first and second transistors, for maintaining the power voltage and the threshold voltage for compensation.
