    Abstract: A gate driver includes a plurality of stages respectively outputting a plurality of gate output signals. An N-th stage of the gate driver (where N is a positive integer) includes a first input part, a second input part, a pull up part, a pull down part, a holding part and a stabilizing part. The first input part transmits a first clock signal to a second node in response to a signal at a first node. The second input part transmits an input signal to the first node in response to a second clock signal. The pull up part pulls up the gate output signal in response to a signal at the second node. The pull down part pulls down the gate output signal in response to the signal at the first node. The holding part maintains the signal at the second node in response to the first clock signal. The stabilizing part stabilizes the gate output signal in response to the signal at the second node and a third clock signal.

    Abstract: Provided are a pixel circuit and a display device having the pixel circuit. The pixel circuit includes an organic light emitting diode, a switching transistor, a storage capacitor, and a driving transistor. The switching transistor is turned off when a scan signal has a first voltage and turned on when the scan signal has a second voltage. The storage capacitor stores a data voltage when the switching transistor is turned on in response to the scan signal. The driving transistor is electrically connected with the organic light emitting diode between a high power supply voltage and a low power supply voltage to provide a driving current to the organic light emitting diode, and includes a first bottom gate electrode that is provided with the first voltage. The driving current corresponds to the data voltage stored in the storage capacitor.
