Abstract: Provided is an organic light-emitting display device which enables a fast and secure repair process without changing optical characteristics. The organic light-emitting display device includes a lower electrode, an organic emitting layer, an upper electrode and an optical compensation layer which are sequentially stacked. The upper electrode is thinner than the lower electrode. An opening is formed by particles in the organic emitting layer and the upper electrode. The opening caused by the particles is extended between the lower electrode and the organic emitting layer.
