Abstract: A display device includes: a display panel including a first pixel, a second pixel adjacent to one side of the first pixel, and a third pixel adjacent to the other side of the first pixel; a first scan driver supplying a first signal to the first to third pixels through a first scan line; a second scan driver supplying a second scan signal to the second and third pixels through a second scan line when a first time elapses after the supply of the first scan signal is started; a data driver supplying a data voltage to a plurality of output lines; and a data divider selectively supplying the data voltage to data lines respectively coupled to the first to third pixels. Each of the second and third pixels includes a switching transistor controlled by the second scan 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.
