Abstract: A rollable display device includes: a soft display panel; a main roller for winding or unwinding the soft display panel; an actuator coupled to the soft display panel to ascend and descend the soft display panel; a housing having the main roller mounted therein, wherein an opening extending in a first direction is defined in a top of the housing to retract and extend the soft display panel therethrough; and an elastic portion having one end coupled to a perimeter of the opening and protruding to cover at least a portion of the opening, wherein the elastic portion includes a rubber portion having a predetermined length along the first direction. The rollable display device may minimize exposure of an interior of the housing to prevent foreign substances from entering.
