Abstract
An emissive display device includes a polycrystalline semiconductor including a channel, source region, and drain region of a driving transistor disposed on a substrate. The device includes a gate electrode of the driving transistor overlapping the channel of the driving transistor, an oxide semiconductor including a channel, a source region, and a drain region of a second transistor disposed on the substrate, and a first connection electrode. The first connection electrode includes a first connector electrically connected to the gate electrode of the driving transistor, a second connector electrically connected to a second electrode of the second transistor, and a main body disposed between the first connector and the second connector. The device includes an initialization voltage line disposed on the substrate and applying an initialization voltage. The initialization voltage line surrounds at least a part of the second connector of the first connection electrode.
