Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2012-0130516 filed in the Korean Intellectual Property Office on November 16, 2012, the entire contents of which are incorporated herein by reference. technical field [0003] Embodiments of the present invention relate to an organic light emitting display device and a method of manufacturing the organic light emitting display device. Background technique [0004] In general, an organic light emitting display device may display colors when electrons and holes respectively injected from an anode and a cathode recombine to emit light. An organic light emitting display device has a structure formed by stacking an anode electrode and a cathode electrode in which a light emitting layer is interposed. [0005] Recently, attempts have been made to realize an organic light emitting display device having a stretchable structure. That is, it is ...
