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.
