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.
