<p>The present invention relates to a scan driver and an organic light emitting display device using the same, capable of preventing a change in characteristics of a transistor and a leakage current by preventing a bias voltage equal to or greater than a source voltage from being applied to the transistor. The scan driver comprises: a plurality of scan driving blocks including a first input terminal to which a frame start signal or an output signal from a previous stage is input, second and third input terminals to which first and second clock signals are transmitted, and an output terminal from which a scan signal is output, wherein each of the scan driving blocks comprises a first transistor transmitting the frame start signal or the output signal from the previous stage to a first node according to the first clock signal, a second transistor outputting the second clock signal as a scan signal according to a voltage level of the first node, and a third transistor limiting a bias voltage of the first transistor corresponding to the voltage of the first node according to an ON resistance value.</p> |
