Abstract
A gate driver according to an embodiment and a display device using the same are discussed. The gate driver can output a gate signal to a pixel circuit having a driving element connected between a first power line and a first node, a light-emitting element connected between the first node and a second power line, and a switching element connected between the first node and a third power line and driven by the gate signal. The gate driver includes a first circuit unit to receive a carry signal from a previous signal transmission unit to charge or discharge a first control node and a second control node, and a second circuit unit having a first buffer transistor and a second buffer transistor configured to output the gate signal based on a first clock signal and a first low potential voltage according to potentials of the first and second control nodes.
