Abstract: A display device includes a plurality of pixels. Each pixel includes a first transistor that controls an amount of current received from a first power supply voltage line connected via a second node to an organic light emitting diode in response to a voltage of a first node, a second transistor connected between a data line and the second node and that includes a first gate electrode connected to a first scan line, a light emitting line connected to a gate electrode of at least one light emitting transistor located in a current path between the first power supply voltage line and the organic light emitting diode, and a seventh transistor connected between one of at least one second gate electrode of the second transistor and the light emitting line. Accordingly, a threshold voltage of a switching transistor included in each of the plurality of pixels may be negatively shifted.
