    • 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.
    • 显示装置包括发光二极管,以及连接在驱动电压和发光二极管之间的第一和第二驱动晶体管,以向发光二极管提供驱动电流。 将极性彼此不同的控制电压或控制电压施加到第一和第二驱动晶体管的控制端子。 第一驱动晶体管具有位于发光二极管的半导体层下方的控制电极,而第二驱动晶体管具有位于半导体层上方的控制电极。 在每个像素处形成两个驱动晶体管,并且其内部占据的区域减小。 极性相差的控制电压被施加到相应的驱动晶体管,基本上防止了驱动晶体管的劣化。
