Abstract: A pixel includes a plurality of transistors, a storage capacitor, and an organic light emitting diode. A first transistor controls the amount of current from a first driving power source to the organic light emitting diode based on a data voltage. A second transistor is connected to a data line and is turned on based on a scan signal. A third transistor coupled to the first transistor and is turned on based on the scan signal. A first stabilizing transistor is coupled to the third transistor or between the first and third transistors and is turned off when the third transistor is turned off.

Abstract: A display device includes a substrate that includes a display area and a non-display area. A driver is disposed in the non-display area, and includes a driver circuit including a transistor and a driver control line transmitting a control signal to the driver circuit. A static electricity blocking line is disposed in the non-display area and circumscribes the display area. The static electricity blocking line at least partially overlaps the driver.
