A pixel circuit of an organic light emitting diode (OLED) display device is provided, which supplies a small current to an organic light emitting diode during stoppage of a display operation. The pixel circuit includes a second driving transistor, which is coupled in parallel with a first driving transistor. A gate control line is used to control the second driving transistor so that a small current can flow into the organic light emitting diode during the stoppage of the display operation. The small current is supplied through the second driving transistor to the organic light emitting diode during the stoppage of the display operation. Thus, the pixel circuit of the OLED display device can reduce or prevent an electric shock applied to the organic light emitting diode at the beginning of the display operation, thereby reducing or preventing deterioration of the characteristics of the organic light emitting diode. |
