Display module and display device

A display device, comprising:

• a power supply assembly and a display module;
• wherein
• the power supply assembly is configured to supply power to the display module;
• and
• the display module comprises:
• a display panel provided with a non-bending region, a first bending region, and a second bending region, wherein an extending direction of the first bending region intersects an extending direction of the second bending region, and an overlapping region of the first bending region and the second bending region is a double-bending region;
• and
• a first support assembly disposed on a non-display side of the display panel, wherein the first support assembly is of a plate-shaped structure, and the first support assembly comprises a first support structure, a second support structure, a third support structure, and a fourth support structure, wherein an orthographic projection of the first support structure on the display panel is in the non-bending region, an orthographic projection of the second support structure on the display panel is at least in the first bending region and is not in the double-bending region, an orthographic projection of the third support structure on the display panel is at least in the second bending region and is not in the double-bending region, and an orthographic projection of the fourth support structure on the display panel is at least in the double-bending region;
• wherein a thickness of each of the second support structure, the third support structure, and the fourth support structure is less than a thickness of the first support structure, and/or a material of each of the second support structure, the third support structure, and the fourth support structure at least comprises a target material, an elasticity modulus of the target material being less than an elasticity modulus of a material of the first support structure;
• and the target material being acquired by filling and curing a liquid material.
