DISPLAY DEVICE, METHOD OF FABRICATING DISPLAY DEVICE, AND ELECTRONIC DEVICE INCLUDING THE SAME

원문 (중국어)

A display device includes a substrate, a bottom electrode disposed on the substrate, a subsidiary metal layer disposed on the substrate and comprising a first auxiliary metal and a second auxiliary metal, wherein the subsidiary metal layer is disposed higher than the bottom electrode relative to an upper surface of the substrate, and a transistor disposed on the subsidiary metal layer. The transistor includes an active layer comprising a source region, a channel region, and a drain region, a gate electrode disposed on the channel region of the active layer, and a source electrode and a drain electrode disposed on the gate electrode. A first vertical extension of the source electrode contacts the first auxiliary metal through a first contact hole penetrating the source region of the active layer. The drain electrode contacts the second auxiliary metal through a second contact hole penetrating the drain region of the active layer.
