1. A flexible display device, comprising:
a first body;
a second body configured to move between a first position and a second position relative to the first body;
a flexible display including a first region fixed to the first body and a second region extending from the first region and coupled to the second body and deformed when the second body moves between the first position and the second position; and
a speaker disposed inside the first body and configured to output a sound,
wherein the first body includes:
a deco frame coupled along an edge of the first region;
a first sound radiation portion forming an outlet through which the sound (sound wave) of the speaker is radiated to the outside of the first body, and formed on the opposite side of the first region based on the deco frame; and
a second sound radiation portion forming an outlet through which the sound (sound wave) of the speaker is radiated to the outside of the first body, and formed between the first region and the deco frame,
wherein the first region includes:
a main region connected to the second region in a first direction and forming a plane parallel to the first direction and a second direction perpendicular to the first direction; and
an edge region extending from the main region in a direction opposite to the first direction to form an end part of the first region, wherein at least a part of the edge region overlaps with the deco frame in a third direction perpendicular to the first direction and the second direction,
wherein the deco frame includes:
a first deco frame parallel to the second direction; and
a second deco frame and a third deco frame extending from opposite ends of the first deco frame and parallel to the first direction, respectively, and
wherein the first sound radiation portion and the second sound radiation portion are formed on opposite sides of the first deco frame, respectively.
