Abstract
A built-in gate driver having an improved reliability and a display device having the same are provided. A transistor controlled by an output signal of a next stage is further provided and thus a node (Q) is rapidly discharged. Accordingly, the multi-output signals due to the reduced discharge of the node (Q) caused by the degradation of the transistor controlled by a node QB can be prevented. By including only one transistor for controlling the charge of the start pulse signal on the node (Q), it is possible to prevent a malfunction from occurring when the transistor connected to the clock is degraded by the periodic clock of a high state. Also, an image quality and the reliability of the gate driver can be improved.
