The first visible area 621 according to certain embodiments may extend along a side located at an upper end of the central visible area 610. The second visible area 622 may extend along a side located at a lower end of the central visible area 610. The third visible area 623 may extend along a side located at one lateral end of the central visible area 610. The fourth visible area 624 may extend along a side located at the other lateral end of the central visible area 610.

Each of the first to fourth corner areas 631 to 634 according to certain embodiments may be implemented in a shape having a curvature.

The first to fourth visible areas 621 to 624 according to certain embodiments may respectively further include the first to fourth visible lateral areas 641 to 644. Each of the first to fourth visible lateral areas 641 to 644 may be disposed to be spaced apart from each other.

For example, a portion between the first and third visible lateral areas 641 and 643 and the first visible corner area 631 may be cut. The cut portion is indicated by a reference numeral 651. A portion between the second and third visible lateral areas 642 and 643 and the second visible corner area 632 may be cut. The cut portion is indicated by a reference numeral 652. A portion between the second and fourth visible lateral areas 642 and 644 and the third visible corner area 633 may be cut. The cut portion is indicated by a reference numeral 653. A portion between the first and fourth visible lateral areas 641 and 644 and the fourth visible corner area 634 may be cut. The cut portion is indicated by a reference numeral 654. Each of the cut portions 651 to 654 is for preventing an elongation difference occurring in each corner area when a pressing process is performed by combining the flexible display 600 and a window. In addition, part of an additional instrument, for example, a support member (e.g., 530 of FIG. 5), may be located to maintain flatness of the display.

Each of the first to fourth visible lateral areas 641 to 644 may fully or partially operate as a display area. If the first visible lateral area 641 partially operates as the display area, a reference numeral 641a may be the display area, and a reference numeral 641b may be a non-display area. A dotted line L1 may represent a border line of the display area and the non-display area. The second to fourth visible lateral areas 642 to 644 may be implemented identically to a first visible lateral area.

Each of the first to fourth visible lateral areas 641 to 644 according to certain embodiments may be implemented of a non-visible area.
