Abstract: A flexible display device can include a display area in which a plurality of sub pixels is disposed and a non-display area which encloses the display area, a flexible substrate including a folding area and a non-folding area with a folding axis, a thin film transistor disposed on the flexible substrate, an organic light emitting diode disposed on the thin film transistor, and an encapsulation layer disposed on the organic light emitting diode. Also, a touch buffer layer is disposed on the encapsulation layer, a touch sensor layer which is disposed on the encapsulation layer and includes a plurality of touch electrodes, and a dam is disposed on the flexible substrate corresponding to the non-display area. Further, an auxiliary spacer is disposed on the flexible substrate so as to overlap at least a part of an outer circumference of the dam.

Abstract: An organic light emitting display and a method for manufacturing the same are discussed. The organic light emitting display includes a substrate, an organic light emitting diode positioned on the substrate, and a bather covering the organic light emitting diode. The organic light emitting diode includes a first electrode, an organic layer, and a second electrode. The barrier includes at least one first block monomer layer and at least one second block monomer layer including inorganic precursors. The at least one first block monomer layer and the at least one second block monomer layer are alternately stacked in a vertical direction.
