Provided is a roll-slide mobile terminal in which a front area of a flexible display unit is variable, for solving a problem of an electric field portion narrowing due to a structure for the variation of the front area, the roll-slide mobile terminal comprising a first frame, a second frame sliding in a first direction with respect to the first frame, the flexible display unit, a first guide rail fixed to the first frame to be parallel to the front area of the flexible display unit and provided in a second direction perpendicular to the first direction, a first slider moving in the second direction along the first guide rail, and a link rotatably fastened to each of the first slider and the second frame to move the second frame according to movement of the first slider.

Roll-slide mobile terminal

A flexible display device is disclosed. The flexible display device includes a first body, a second body, a flexible display, a first wheel, and a second wheel. The first wheel and the second wheel may be rotatably coupled to the first body. A lateral surface of the first wheel comes into contact with a first rolling surface of the second body in a first contact direction, and a lateral surface of the second wheel comes into contact with a second rolling surface of the second body in a second contact direction, wherein the first contact direction and the second contact direction are symmetrical to each other about a reference surface. When the second body moves relative to the first body in a first direction or in a direction opposite to the first direction, the first wheel and the second wheel roll on the first rolling surface and the second rolling surface.
