1. A display device, comprising:
a flexible display panel bendable in a first direction and having a bendable area;
a middle frame encompassing a periphery of the flexible display panel; and
a stretching and folding assembly disposed in the bendable area and comprising:
an elastic assembly covering the bendable area and a part of the middle frame corresponding to the bendable area;
a plurality of connecting blocks disposed respectively at opposite ends of the elastic assembly in a second direction perpendicular to the first direction;
a plurality of connecting pieces each disposed between two adjacent ones of the connecting blocks to connect the two adjacent ones of the connecting blocks to each other, the connecting pieces being configured to, when the flexible display panel is bent, cause the connecting blocks to drive the part of the middle frame corresponding to the bendable area to be bent;
a strengthening bar fixed to the elastic assembly to increase stability of the bendable area, wherein the strengthening bar is plastically melted to be connected to the elastic assembly; and
a plurality of connecting patches disposed respectively at opposite ends of the strengthening bar in the second direction to fix the strengthening bar.
