ABSTRACT:
A pixel circuit able to stably and correctly supply a current having a desired value to a light emitting diode of each pixel without being influenced by variation of a threshold value of an active element inside the pixel or variation of mobility and able to display a high quality image as a result of this, wherein a TFT as a fourth switch is turned on together with a TFT as a second switch at the time of an auto-zero operation, a reference current line is connected to a drive transistor of the pixel through a first node, and the variation of the threshold value Vth is corrected, whereby variation of the on current due to the mobility at the time of a white display can be suppressed and the uniformity with respect to variation in the mobility can be greatly enhanced, and a display device and a driving method of the pixel circuit.
