Abstract
An improved organic light-emitting display apparatus prevents damage of wiring due to a mask during the manufacturing process, and a manufacturing method thereof. An organic light-emitting display apparatus includes a display unit formed on a substrate, a pad unit formed at one outer side of the display unit on the substrate, a wiring unit formed as a multilayer structure on the substrate to couple the display unit to the pad unit, a thin film encapsulating layer covering the display unit, and a protrusion unit that does not overlap the uppermost layer of wiring of the multilayered wiring unit.
Claims25
An organic light-emitting display apparatus comprising:
- a display unit on a substrate;
- a pad unit at one outer side of the display unit on the substrate;
