1. An organic light-emitting display device comprising:

  • a substrate;

    a driving thin film transistor on the substrate;

    an organic light emitting diode on an upper portion of the driving thin film transistor;

    an encapsulation structure on an upper portion of the organic light-emitting diode and sealing the organic light-emitting diode; and

    a DAM at an outermost portion of the substrate,wherein the DAM comprises an inorganic layer and a first metallic DAM,wherein the inorganic layer extends between the organic light emitting diode and the substrate,wherein the encapsulation structure comprises alternately stacked thin film encapsulation organic layers and thin film encapsulation inorganic layers, andwherein the thin film encapsulation inorganic layers extend over the first metallic DAM, and the organic light emitting diode is between the inorganic layer of the DAM and the thin film encapsulation inorganic layers.
