a first body;

a flexible display configured to be inserted into or withdrawn from the first body while being deformed by an external force;

a rotation member configured to be rotatable inside the first body;

a second body coupled to one end of the flexible display;

a rear plate coupled to a rear surface portion of the flexible display to be deformed together with the flexible display;

a rear plate fixing groove extending along an extension direction of the rotation member; and

a bent end portion of the rear plate inserted into and fixed to the rear plate fixing groove,

wherein the flexible display is deformed so as to be rolled while being inserted into the first body, and is deformed so as to be unrolled while being withdrawn from the first body,

wherein one end of the rear plate extends beyond the other end of the flexible display, which is different from the one end of the flexible display to which the second body is coupled to form an extended portion of the rear plate,

wherein the one end of the flexible display is provided with a printed circuit board, and

wherein the bent end portion is formed at one end of the extended portion of the rear plate, thereby forming the extended portion that exists between the flexible display and the bent end portion and is formed integrally with the bent end portion.
