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 having an opening partially exposing the thin film transistor;

    a first anode disposed on the first passivation layer in the first luminescent device region;

    a second anode disposed on the first passivation layer in the second luminescent device region;

    a second passivation layer partially covering the first anode and the second anode so as to partially expose the first anode and the second anode, the exposed first anode having a first luminescent region and a first series-connected region and the exposed second anode having a second luminescent region and a second series-connected region;

    a pillar substantially disposed on the second passivation layer in the thin film transistor region, the first luminescent device region and the second luminescent device region, the pillar substantially surrounding the first luminescent region and the second luminescent region;

    an organic luminescent layer covering the first anode in the first luminescent region and the second anode in the second luminescent region;

    a first cathode covering the organic luminescent layer in the first luminescent region and 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 cathode covering the organic luminescent layer in the second luminescent region and electrically connected to the first series-connected region.
