Abstract: A display device includes a substrate, data lines arranged on the substrate, the data lines to which data voltages are applied, scan lines arranged on the substrate, the scan lines to which scan signals are applied, and a pixel connected to one of the data lines and at least one of the scan lines. The pixel includes a light emitting element, a driving transistor which supplies a driving current flowing between a first electrode and a second electrode to the light emitting element in accordance with the data voltage of the data line applied to a gate electrode, a first transistor between the gate electrode and second electrode of the driving transistor, a shielding electrode overlapping at least a part of the first transistor in a thickness direction of the substrate. The shielding electrode does not overlap the data lines in the thickness direction of the substrate.
