1. A method for manufacturing an organic light emitting display device, comprising:
forming an overcoat layer with a plurality of micro lenses in an emission area on a substrate, the substrate being divided into the emission area and a non-emission area;
forming a first electrode on the overcoat layer in the emission area;
forming an organic stacking layer on the first electrode in the emission area, the organic stacking layer including an organic emission layer, at least one surface of the organic stacking layer having a flat surface in the emission area;
forming a reflective layer disposed between the organic emission layer and the first electrode in the emission area; and
forming a second electrode on the organic stacking layer in the emission area and the non-emission area,
wherein a micro lens from the plurality of micro lenses is divided into a first region, a second region, a third region, and a fourth region,
the first region corresponds to a concave region of the micro lens,
the second region corresponds to a first inclined surface of the micro lens, the first inclined surface extended from the concave region,
the third region corresponds to a second inclined surface extended from the first inclined surface, and
the fourth region corresponds to a convex region of the micro lens, and
wherein the reflective layer is formed only in the first to third regions or the first and second regions of the micro lens.
