Abstract
An emissive display device includes: a light emitting diode; an n-type driving transistor comprising a first driving gate electrode, a first electrode receiving a driving voltage, a second electrode transferring an output current to the anode, and a second driving gate electrode; a second transistor connected to a data line; a third transistor configured to connect the first electrode and the first driving gate electrode of the driving transistor; a storage capacitor comprising a first storage electrode and a second storage electrode connected to the first driving gate electrode; a ninth transistor transferring an overlapping electrode voltage to the second driving gate electrode; an overlapping electrode voltage line crossing the data line and receiving the overlapping electrode voltage; and a shielding electrode at an intersection of the data line and the overlapping electrode voltage line and between the data line and the overlapping electrode voltage line.
