Organic light emitting display device and method of manufacturing organic light emitting display device

A method of manufacturing an organic light emitting display device, comprising:

• forming an insulation layer on a substrate;
• forming a first electrode on the insulation layer;
• forming at least one reflecting structure at the first electrode;
• forming a pixel defining layer on the first electrode, the pixel defining layer defining a luminescent region and a non-luminescent region;
• forming at least one light emitting structure on the first electrode in the luminescent region, the at least one light emitting structure being surrounded by the at least one reflecting structure;
• and
• forming a second electrode on the at least one light emitting structure and the pixel defining layer;
• wherein forming the reflecting structure comprises partially etching the first electrode adjacent to an area between the luminescent region and the non-luminescent region, and forming the reflecting structure at the etched portion of the first electrode.
