Abstract
An organic light-emitting diode (OLED) display includes: a substrate on which an organic light-emitting element is formed; an organic light-emitting element on a substrate; a first inorganic layer on the organic light-emitting element and made substantially of hydrogenated silicon nitride (SiN:H); an organic layer on a portion of the first inorganic layer; and a second inorganic layer on and completely covering the organic layer. Edges of the second inorganic layer come in contact with the first inorganic layer. A ratio of a number of oxygen atoms to silicon atoms contained in the first inorganic layer ranges from 0.12 to 0.19, and a ratio of a number of nitrogen atoms to silicon atoms contained in the first inorganic layer ranges from 0.9 to 1.5. The first inorganic layer and the second inorganic layer have substantially the same composition.
