1. A display device, comprising:
a display panel in which a plurality of sub-pixels is disposed;
a data driver configured to supply a plurality of data voltages to the plurality of sub-pixels through a plurality of data lines; and
a gate driver configured to supply a plurality of gate signals to the plurality of sub-pixels through a plurality of gate lines,
wherein each of the plurality of sub-pixels includes a light emitting diode, a driving transistor, and a variable resistance circuit disposed in series between a low-potential voltage terminal and a high-potential voltage terminal, and
when each of the plurality of sub-pixels implements a low grayscale, the variable resistance circuit increases a resistance between the high-potential voltage terminal and the driving transistor.
