A rollable displace device is provided. The rollable display device includes a flexible display assembly coupled to a roller that is configured to be wound and unwound around the roller. When the display panel is wound around the roller, the display panel is received in a housing. When the display panel is unwound from the roller, the display panel extends from the housing. The display device includes at least one support link coupled to the display panel and configured to extend and contract in response to the unwinding and winding of the display panel, respectively. The at least one support link supports the display panel in the unwound state and reduces or prevents overturning of the display panel in the unwound state.
