A display device includes a light emitting diode, and first and second driving transistors connected between a driving voltage and the light emitting diode to supply driving electric current to the light emitting diode. A control voltage or control voltages differentiated in polarity from each other is/are applied to control terminals of the first and the second driving transistors. The first driving transistor has a control electrode located below a semiconductor layer of the light emitting diode while the second driving transistor has a control electrode located over the semiconductor layer. Two driving transistors are formed at each pixel, and an area occupied thereof within the pixel is reduced. Control voltages differentiated in polarity from each other are applied to the respective driving transistors, substantially preventing deterioration of the driving transistors.
