Abstract
A display device includes: a display panel provided with multiple pixels; a driving circuit; and a power generator, wherein each of the pixels includes: a first switching transistor of which a gate electrode is connected to the gate line, of which a first electrode is connected to the data line, and of which a second electrode is connected to a first node; a driving transistor of which a gate electrode is connected to a reference line and thus receives a reference voltage supplied from the power generator, of which a first electrode is connected to the first node, and of which a second electrode is connected to a second node; and a light-emitting device of which an anode electrode is connected to the second node, and of which a cathode electrode is connected to a power line through which the power generator supplies a low-potential power supply voltage.
