A display panel includes a pixel connected to a scan line and a data line, and a lighting test circuit which provides a lighting test voltage to the pixel through the data line. The lighting test circuit includes a first test transistor including a first electrode which receives the lighting test voltage, a second electrode and a gate electrode which receives a first test control signal, and a second test transistor including a first electrode connected to the second electrode of the first test transistor, a second electrode connected to the data line and a gate electrode which receives a second test control signal.
