Abstract

A flexible electroluminescent display apparatus can include a flexible substrate including an active area and a bending area extending from the active area; a thin film transistor disposed on the active area and including a semiconductor layer, a gate electrode, a source electrode and a drain electrode; an planarization layer disposed on the thin film transistor; a light emitting element disposed on the planarization layer in the active area and connected to the thin film transistor through a connection electrode; and a first wiring line and a second wiring line disposed in the bending area, in which the first wiring line, the source electrode and the drain electrode are configured as a same layer, and the second wiring line and the connection electrode are configured as a same layer, and the first wiring line and the second wiring line are directly connected to each other.
