Gate driver and electroluminescence display device using the same

An electroluminescence display device and a gate driver are provided. An electroluminescence display device includes: an emission line (EL), subpixels connected to the EL, and an emission driver supplying an emission signal to the EL, the emission driver including a plurality of stages, a kth stage including: a first output (O1) node connected to the EL, a second output (O2) node, a Q node, a pull-down circuit and a pull-up circuit respectively controlled by the Q and O2 nodes and providing a voltage to the O1 node, a first controller receiving an O1 node voltage of a (k−1)th stage or a first start signal, a second controller receiving an O2 node voltage of the (k−1)th stage or a second start signal, a third controller controlling the O2 node voltage, and a fourth controller controlled by the O2 node, wherein 'k' is a natural number ≥1.
