A display device includes a pixel electrode that includes a first sub-pixel electrode and a second sub-pixel electrode, a first thin film transistor connected to the first sub-pixel electrode, a second thin film transistor connected to the second sub-pixel electrode, an assistance capacitor connected to the first sub-pixel electrode, and a third thin film transistor connected to the assistance capacitor and the second sub-pixel electrode. The third thin film transistor includes a gate electrode, a source electrode overlapping the gate electrode and connected to the second sub-pixel electrode, and a drain electrode connected to the assistance capacitor, and a parasitic capacitance between the gate electrode and the drain electrode is equal to or less than a parasitic capacitance between the gate electrode and the source electrode.
