Claim:
1. An organic light emitting display, comprising: a substrate comprising a display region and a non-display region outside the display region; an organic light emitting unit disposed in the display region, the organic light emitting unit comprising a first electrode, an intermediate layer, and a second electrode sequentially stacked on the substrate; and an encapsulation unit comprising: an organic film disposed on the organic light emitting unit; a first inorganic film disposed on the display region and covering the organic film, the first inorganic film comprising a first low temperature viscosity transition (LVT) inorganic material having a first viscosity transition temperature; and a second inorganic film disposed in direct contact with the non-display region and adjacent to the first inorganic film without directly contacting any portion of the organic film, the second inorganic film comprising a second LVT inorganic material having a second viscosity transition temperature lower than the first viscosity transition temperature.
