Abstract
A display panel includes a display panel test circuit including an open-short test transistor including a gate electrode which receives a test gate signal, a first electrode which receives an open-short test voltage, and a second electrode connected to a data line which transmits a data voltage and an electrostatic discharge protection circuit including: a first electrostatic discharge diode including a cathode electrode connected to the data line and an anode electrode which receives a first voltage; a first switching element which determines a minimum voltage of the display panel as the first voltage under a first condition and determines an electrostatic discharge low potential voltage higher than the minimum voltage of the display panel as the first voltage under a second condition; and a second electrostatic discharge diode including a cathode electrode which receives a second voltage and an anode electrode connected to the data line.
