    Abstract: A display device includes a pixel, a first control pad, a second control pad, and a first dummy pad. The pixel may emit light with luminance corresponding to a data signal. Supply of the data signal to the pixel depends on a first control signal and a second control signal. The first control pad is connected to a first control line for supplying the first control signal. The second control pad is connected to a second control line for supplying the second control signal. The first dummy pad is positioned between the first control pad and the second control pad and may receive a first dummy signal. A voltage level of the first dummy signal is in a range from a voltage level of the first control signal to a voltage level of the second control signal.

    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.
