1. An organic light emitting device comprising:

  • a substrate;

    a first signal line formed on the substrate;

    a second signal line formed perpendicularly to the first signal line;

    a plurality of thin film transistors formed on the substrate and electrically connected to the first and second signal lines;

    a first passivation layer formed on the thin film transistors and having a concavo-convex surface;

    a first electrode formed on the first passivation layer;

    a partition formed on the first electrode and having an opening extending to the first electrode;

    a light emitting member formed on the first electrode and in the opening; and

    a second electrode formed on the light emitting member,wherein refractive indices of the light emitting member and the first passivation layer are different, and refractive indices of the first passivation layer and the first electrode are different.
