Abstract: A light-emitting display device configured such that an area in which particles are generated is determined in an inspection process after formation of a light-emitting device and correspondingly a cover pattern is formed and a method of manufacturing the same. The particles are prevented from serving as a permeation path of impurities, whereby reliability of the light-emitting display device is improved.
