ORGANIC LIGHT-EMITTING DISPLAY APPARATUS AND METHOD OF MANUFACTURING THE SAME

摘要

An organic light-emitting display apparatus including a substrate; a display unit which defines an active area of the substrate and includes a thin film transistor; concave-convex portions protruded from the substrate in an area outside the active area; and an encapsulation layer which encapsulates the display unit. The thin film transistor includes an active layer, a gate insulating layer on the active layer, a gate electrode, a source electrode, a drain electrode, and an interlayer insulating layer between the gate electrode and the source electrode, and between the gate electrode and the drain electrode. The concave-convex portions include portions of the gate insulating layer and the interlayer insulating layer, and the encapsulation layer covers the concave-convex portions.
