Display panel and display device including the same

An electronic device comprising:

• a display panel including pixels, a display panel test circuit, and an electrostatic discharge protection circuit which are connected to a data line which transmits a data voltage;
• a flexible circuit board which drives the display panel and outputs an electrostatic discharge low potential voltage;
• and
• a processor which controls the flexible circuit board,
• wherein the display panel test circuit includes 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 the data line,
• wherein the electrostatic discharge protection circuit includes:
• 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 the 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, and
• wherein a voltage difference between the data voltage and the electrostatic discharge low potential voltage is less than a voltage difference between the data voltage and the minimum voltage of the display panel.
