A pixel capable of reducing leakage current (to display an image with desired brightness) is provided. The pixel includes: an organic light emitting diode (OLED) coupled to a second power source; a first transistor for controlling an amount of current that flows from a first power source to the second power source via the OLED; a second transistor coupled between a data line and the first transistor, and configured to turn on when a scan signal is supplied to a scan line; a third transistor and a fourth transistor serially coupled between the first transistor and an initializing power source; and a fifth transistor coupled between a first node coupled to a gate electrode of the first transistor, and a second node that is a common node between the third transistor and the fourth transistor, and configured to turn off in a period where current is supplied to the OLED.
