Abstract: A rollable display device includes a roller defining a rolling direction, and a rollable display unit. A first side of the rollable display unit is fixed to the roller, and the rollable display unit includes a plurality of spacers spaced apart from one another and arranged in the rolling direction. Heights of the spacers disposed near a second side of the rollable display unit opposing the first side are greater than heights of the spacers disposed near the first side of the rollable display unit.

Abstract: An organic light emitting device includes a substrate. An organic light emitting diode is disposed on the substrate. A thin film encapsulation layer is disposed over the organic light emitting diode. The thin film encapsulation layer includes at least one organic layer. An organic passivation layer is disposed directly on the thin film encapsulation layer. The organic passivation layer has a smaller Young's modulus than the organic layer of the thin film encapsulation layer.
