Abstract:
Disclosed herein are a gate driver including at least two output buffers to drive at least two gate lines and capable of reducing an output deviation of each output buffer, and a flat panel display device including the same. The gate driver includes a plurality of gate-in-panels (GIPs) for sequentially supplying scan signals to a plurality of gate lines. Each GIP includes one carry signal output unit and at least two scan signal output units to drive at least two gate lines, and the carry signal output unit includes a pull-up transistor controlled by a voltage of a first node, a pull-down transistor controlled by a voltage of a second node, and a boosting capacitor formed between gate and source electrodes of the pull-up transistor.
