Abstract
A method of manufacturing an organic light emitting display device includes forming a plurality of display structures on a lower substrate, forming a top protection film including a plurality of top opening patterns on the lower substrate and the display structures such that the top opening patterns do not overlap the display structures, cutting the lower substrate between two adjacent display structures among the plurality of display structures along a first cutting line that is located at at least a portion of the top opening patterns, and separating the lower substrate to form a plurality of display panels each including the display structure and a portion of the lower substrate.
