1. A display device, comprising:
a light-emitting element;
a first transistor connected between a driving voltage line and the light-emitting element, the first transistor including:
a first gate electrode and a second gate electrode that face each other; and
an active layer between the first gate electrode and the second gate electrode;
a first data line connected to the first gate electrode of the first transistor;
a second data line connected to the second gate electrode of the first transistor; and
a data driver connected to the first data line and the second data line, wherein
the data driver applies a first data voltage to the first data line and applies a second data voltage having a different voltage from the first data voltage to the second data line,
a magnitude of the second data voltage varies depending on a magnitude of the first data voltage, and
in case that the first data voltage is less than a lower limit value, the magnitude of the second data voltage maintains as a value corresponding to the first data voltage having the lower limit value.
