Metal support and flexible display device

A flexible display device, comprising:

• a flexible display panel;
• a backlight assembly;
• and
• a metal support,
• wherein the metal support is located on a backlight side of the flexible display panel, and the backlight assembly is arranged between the flexible display panel and the metal support;
• wherein the metal support comprises a bendable region, a non-bendable region, and at least one patterned region covering at least the bendable region, wherein the bendable region is capable of bending along a first direction, a plurality of columns of hollowed-out parts arranged side by side along the first direction are arranged in the patterned region, each column of the plurality of columns of hollowed-out parts comprises a plurality of openings arranged at intervals along a second direction, the patterned region comprises two first edges arranged opposite to each other in the first direction, a column of the plurality of columns of hollowed-out parts near one of the first edges extends along a first arc, and a column of the plurality of columns of hollowed-out parts near the other first edge extends along a second arc, with convex side of the first arc is oriented toward convex side of the second arc, wherein the first direction and the second direction are perpendicular, and both the first direction and the second direction are parallel to a plane of the metal support;
• wherein the bendable region includes a first center line extending in the first direction and a second center line extending in the second direction, the plurality of columns of hollowed-out parts are symmetrically distributed about the first center line, and symmetrically distributed about the second center line, and the first center line is perpendicular to the second center line;
• wherein the metal support comprises a first patterned region at a middle part and a second patterned region symmetrically disposed on opposite sides of the first patterned region in the first direction, the first patterned region comprises at least a first column of the plurality of columns of hollowed-out parts, and a long axis of each of the plurality of openings in the first column of the plurality of columns of hollowed-out parts coincides with the second center line.
