    IPC: G09G3/32

    Abstract: A display device includes pixels, a scan driver, an emission driver, and a data driver. A pixel of an i-th horizontal line includes a light emitting element, a first transistor including a first electrode connected to a first node, a second transistor including a gate electrode connected to an (i+x)-th emission control line and connected to one of the data lines, a third transistor including a gate electrode connected to an (i+y)-th emission control line, and connected between the second transistor and the first node, a fourth transistor connected between a third node connected to a second electrode of the first transistor and a second node, and turned on by a scan signal supplied to an i-th scan line, and a fifth transistor connected between the first power and the first node, and turned off by the emission control signal supplied to an i-th emission control line.

    IPC: H01L27/32 ,  H01L51/52

    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.
