Abstract: A gate driver and a display device comprising the same are discussed. The gate driver can comprise a plurality of stages for individually driving a plurality of gate lines by a combination of a plurality of group signals, a plurality of block signals, and a plurality of clock signals. Each of the plurality of stages driven independently can include an output buffer including a pull-up transistor configured to generate and output a gate-on level of a scan signal under the control of a first node, and a pull-down transistor configured to generate and output a gate-off level of the scan signal under the control of a second node. Each stage can further include a first controller configured to control the first node, and a second controller configured to control the second node to be opposite to the operation of the first node.
