Abstract: Provided is a display device. The display device comprises a substrate, and a plurality of sub-pixels disposed on the substrate and including alight emitting element and a sub-pixel circuit driving the light emitting element. The sub-pixel circuit comprises a driving transistor controlling a driving current flowing through the light emitting element, a first transistor and a second transistor connected in series between a first node, which is a drain electrode of the driving transistor, and a second node, which is a gate electrode of the driving transistor, to receive the same scan signal, and a gate auxiliary electrode disposed on a gate electrode of the first transistor or the second transistor. The gate auxiliary electrode is connected to the gate electrode of the first transistor or the second transistor.
