A scan driving circuit and an organic light emitting display using the same are provided to reduce power consumption by removing a static current path, to minimize leakage current by not charging an output terminal in high-output, and to increase operation speed by performing bootstrap in low-output. A transfer unit includes a first transistor(M1) for receiving a start pulse or an output voltage of the previous stage and including a gate terminal connected to a first clock terminal, and a third transistor(M3) including a gate terminal connected to an output terminal of the first transistor. The third transistor is connected between a second clock terminal and a first node(N1). An inversion unit includes a fourth transistor(M4) for receiving the start pulse or the output voltage of the previous stage and including a gate terminal connected with the first clock terminal, a fifth transistor(M5) including a gate terminal connected to the first clock terminal, and a six transistor(M6) including a gate terminal connected to an output terminal of the fourth transistor. The fifth transistor is connected between a second power source and a second node. The sixth transistor is connected between the first clock terminal and a second node(N2). A buffer unit includes an eighth transistor(M8) including a gate terminal connected to the second node. The eighth transistor is connected between a first power source(VDD) and an output line.
