Display device

A display device, comprising:

• a data driver configured to generate an output signal corresponding to input image data;
• a demultiplexer configured to divide the output signal into a plurality of data signals;
• a display unit including a plurality of pixels, wherein each of the pixels has a driving transistor applied to a driving voltage from a power source;
• a test unit connected to the driving transistor and configured to apply the data signals to the pixels according to a control signal, wherein the test unit is disposed between the demultiplexer and the display unit;
• a first power wire disposed between the display unit and the test unit;
• a second power wire disposed between the test unit and the data driver;
• a bridge disposed between the first power wire and the second power wire, and
• the driving voltage applied to the pixels though the first power wire, the second power wire, and the bridge.
