Organic light emitting display apparatus

An apparatus includes a plurality of pixels on a substrate; a gate driver disposed outside of the plurality of pixels; a common voltage line disposed outside both of the gate driver and the plurality of pixels, the common voltage line having a first cross-sectional width; a dam structure configured to surround the plurality of pixels and disposed on at least a portion of the common voltage line, the dam structure having a second cross-sectional width narrower than the first cross-sectional width; a first inorganic encapsulation layer configured to cover the plurality of pixels, the gate driver, the common voltage line and the dam structure; a cover layer disposed on the first inorganic encapsulation layer and configured to be surrounded by the dam structure; and a second encapsulation layer disposed on the first encapsulation layer and the cover layer.

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.
