1. A display panel comprising:
a first data signal line;
a second data signal line; and
an electrostatic protection circuit comprising a first protection circuit electrically connected between the first data signal line and the second data signal line,
wherein the first protection circuit comprises:
a first dual-gate transistor connected between the first data signal line and the second data signal line, and comprising a gate electrode and a lower gate electrode;
a first resistor connected between the gate electrode of the first dual-gate transistor and the second data signal line;
a first capacitor connected between the gate electrode of the first dual-gate transistor and the second data signal line; and
a second capacitor connected between the lower gate electrode of the first dual-gate transistor and the second data signal line,
wherein the lower gate electrode of the first dual-gate transistor receives a reference voltage.
