Abstract:
1. A pixel structure of an organic electroluminescent display panel, comprising: a substrate having a thin film transistor region, a first luminescent device region, and a second luminescent device region; a thin film transistor disposed in the thin film transistor region of the substrate; a first passivation layer disposed on the substrate, the first passivation layer having an opening partially exposing the thin film transistor; a first bottom electrode disposed on the first passivation layer in the first luminescent device region; a second bottom electrode disposed on the first passivation layer in the second luminescent device region; a second passivation layer disposed on the first bottom electrode and the second bottom electrode so as to at least partially expose the first bottom electrode and the second bottom electrode, the exposed first bottom electrode having a first luminescent region and a first series-connected region, and the exposed second bottom electrode having a second luminescent region and a second series-connected region; a partition substantially disposed on the second passivation layer and substantially overlapped with at least one of the first series-connected region and the second series-connected region; a first organic luminescent layer disposed on the first bottom electrode, and a second organic luminescent layer disposed on the second bottom electrode in the second luminescent region; a first top electrode disposed on the first organic luminescent layer in the first luminescent region and disposed on a part of the first passivation layer in the thin film transistor region, and electrically connected to the thin film transistor through the opening of the first passivation layer; and a second top electrode disposed on the second organic luminescent layer in the second luminescent region and electrically connected to the first series-connected region.
