According to an embodiment, the upper surface of the bending plate 1320 may be attached to the lower surface of the display 610 through a first adhesive member 1330 (eg, a first adhesive tape). For example, the first adhesive member 1330 may be attached to the entire upper surface of the bending plate 1320 . The lower surface of the bending plate 1320 may be attached to the upper surface (eg, the upper surface 1311 of FIG. 15A ) of the multi-bars 1310 through a separate second adhesive member (eg, a second adhesive tape). For example, the second adhesive member 1340 may be attached to the entire lower surface of the bending plate 1320 .

According to an embodiment, the lower surface of the bending plate 1320 may be attached to the upper surface (eg, the upper surface 1311 of FIG. 15A ) of the multi-bars 1310 through a welding method.

A section 1324 (eg, an interlocking section) may be included. At least a portion of the support plate 1322 may be uniformly cut to form a stretch section 1324 . When the bendable section of the display 610 (eg, the bendable section 610b of FIG. 10 ) moves in the x-axis direction via the bend 601 , a compressive force is applied, and the interval between the multi-bars 1310 . (d) becomes narrower. When the distance d between the multi-bars 1310 is narrowed, interference between the multi-bars 1310 may occur, and a local tensile stress may occur in a section between the multi-bars 1310 .
