Abstract
The present application provides a display device and a driving method thereof which can drive a driving transistor with lower power consumption when displaying an image. An organic EL display device applies voltage to switch on/off a driving transistor (M) to a bottom gate electrode () of the driving transistor (M) having a double gate structure, and applies a data voltage (Vdata) depending on data signals to a top gate electrode () as back gate voltage (Vbg). With this configuration, variation width of the voltage value can be smaller in comparison with a case to apply the data voltage to the bottom gate electrode ().
