Abstract: A flexible display panel of an expandable display device includes a first side with a display unit, and a second side opposite to the first side. A bending guide includes an external guide that faces part of the first side and has a first curved side, and an internal guide that faces part of the second side and has a second curved side. A slider that slides on the bending guide is attached to, one end portion of the flexible display panel. A radius of the first curved side is greater than a radius of the second curved side. When the slider moves toward the bending guide, the first side contacts the first curved side and is bent by the first curved side, and when the slider moves away from the bending guide, the second side contacts the second curved side and is bent by the second curved side.

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.
