Abstract:
An organic light-emitting display device is disclosed. The organic light-emitting display device may include a substrate, an organic light-emitting portion provided on the substrate, a first inorganic film that seals and covers the organic light-emitting portion, and a second inorganic film provided on the first inorganic film and including a low temperature viscosity transition (LVT) inorganic material. A coefficient of thermal expansion (CTE) of the first inorganic film may be smaller than a CTE of the second inorganic film.
