1. An organic light emitting diode display device comprising:

  • a substrate divided into an emissive area and a non-emissive area;

    an overcoat layer disposed on the substrate and having a plurality of micro lenses in the emissive area and at least one depression in the non-emissive area, each of the plurality of micro lenses comprising a concave portion and a connecting portion;

    a thin film transistor disposed in the non-emissive area and covered by the overcoat layer;

    a first electrode disposed on the overcoat layer and connected to the thin film transistor through a contact hole formed in the overcoat layer;

    a bank pattern disposed in the non-emissive area so as to be superposed on the at least one depression and the contact hole;

    an organic light emitting layer disposed on the first electrode; and

    a second electrode disposed on the organic light emitting layer,wherein each of the first electrode, the organic light emitting layer and the second electrode has a shape according to the plurality of micro lenses in the emissive area,wherein the at least one depression has a different shape from a shape of the concave portion, andwherein the at least one depression surrounds the emissive area in a plan view.
