Abstract
An organic light emitting display comprises pixels connected to gate lines, and a gate driving circuit to supply a gate signal to at least one gate line, and having stages connected to each other in a cascading way. A n(n is a positive integer) stage of the gate driving circuit includes a Q1 node charging unit to charge a Q1 node to a turn-on voltage using first and second clock signals in reverse-phase, and a pull-up transistor to apply the turn-on voltage to an output terminal in response to a Q1 node voltage. The Q1 node charging unit includes a first charging unit to charge the Q1 node voltage to the turn-on voltage using the second clock signal; and a second charging unit to charge a Q2 node, coupled to the Q1 node, using the first clock signal in a section where the Q1 node has the turn-on voltage.
