An organic light emitting display device includes a substrate in which an active area and a bending area are defined, a thin film transistor on the substrate in the active area, a first wiring line on the substrate in the bending area, a first planarization layer which is on the thin film transistor in the active area and on the first wiring line in the bending area, a second wiring line on the first planarization layer in the bending area, a second planarization layer which is on the first planarization layer in the active area and on the first planarization layer and the second wiring line in the bending area, an organic light emitting element on the second planarization layer in the active area, and a micro-cover layer on the second planarization layer in the bending area.
