Abstract: Disclosed are a display device and a method for manufacturing a cover thereof. A method for manufacturing a cover of a display device comprises: (a) a step in which a BM printing layer is formed on the front surface of a transparent film, and a release film is attached thereto; (b) a step in which the release film is cut along the BM printing layer; (c) a step in which the release film attached to the front surface of the transparent film is removed; (d) a step in which an abrasion-resistant coating layer is formed on the front surface of the transparent film; and (e) a step in which the release film attached to the BM printing layer is removed.

Abstract: A flexible display device is disclosed. The flexible display device includes a first body, a second body, a flexible display, an actuator, and a first sensor. The second body reciprocates relative to the first body along a first direction between a first position and a second position. The flexible display includes a first region and a second region. As the second body moves from the first position to the second position, the area of the second region, forming the same plane as the first region, increases. The actuator may be operated such that the second body is moved toward the second position in response to free fall being detected by the first sensor, and damage to the flexible display device due to impact with the ground may thereby be reduced.
