Abstract
An OLED display apparatus includes a repair portion such that outgas possibly generated during a process of repairing a defective bright spot pixel by making a defective bright spot into a dark spot can be reduced or minimized. At least one pixel including at least one driving element and an organic light-emitting element is disposed on a substrate. A protective layer or a planarization layer for protecting the driving element is on a wiring electrode extended from a source electrode or a drain electrode of the driving element. At least a part of the protective layer or the planarization layer are removed such that outgas generated during a process of repairing the pixel by using a laser is reduced. The at least a part of the protective layer or the planarization layer is defined as a repair portion.
