1. A flexible display device comprising:
a first body;
a second body configured to be movable relative to the first body;
a flexible display disposed to be exposed to a front surface of the first body and a rear surface of the second body; and
a link module that guides the first body and the second body to move relative to each other,
wherein the link module fixes the first body and the second body to each other to prevent or reduce the first body and the second body from moving closer to or away from each other when the first body and the second body are spaced apart by a preset distance,
wherein the first body and the second body are configured to implement:
a first state in which an area of the flexible display exposed through a rear surface portion of the second body is the largest when the first body and the second body are positioned adjacent to each other;
a second state in which an area of the flexible display exposed through a front surface portion of the first body is the largest when the first body and the second body are positioned away from each other; and
a stroke state in which the first state and the second state are switched from each other, respectively,
wherein the link module fixes the first body and the second body to each other to prevent or reduce the first body and the second body from being switched to the stroke state from the second state,
wherein the first body and the second body are configured to implement a released state in which the first body and the second body are disposed further apart than the second state, and
wherein the link module is configured to switch the first body and the second body back to the stroke state from the released state.
