Abstract: According to an aspect of the present disclosure, a display device includes a display panel in which a plurality of sub-pixels is disposed. Also, the display device includes a data driver configured to supply a plurality of data voltages to the plurality of sub-pixels through a plurality of data lines. Further, the display device includes a gate driver configured to supply a plurality of gate signals to the plurality of sub-pixels through a plurality of gate lines. 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. 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. Thus, a low grayscale can be normally implemented.
