A display apparatus, comprising a display panel, wherein

• the display panel comprises:
• a display substrate, having a display area, a non-display area, and a bendable area located between the display area and the non-display area;
• a back film, located on a side away from a light exit surface of the display substrate, wherein the back film comprises a first support area and a second support area, a projection of the first support area on the display substrate at least overlaps with the display area, and a projection of the second support area on the display substrate is located within the non-display area;
• and
• a heat dissipation film, located on a side of the back film away from the display substrate, wherein an orthographic projection of the heat dissipation film on the back film is located within the first support area, a surface of the heat dissipation film away from the display substrate is provided with a groove, and the groove is filled with an adhesive, wherein
• after the bendable area is bent, the non-display area and the second support area are located on a side of the heat dissipation film away from the first support area, and the second support area covers the groove and is in contact with the adhesive;
• and
• an orthographic projection of the groove on the display substrate is located within a portion, not overlapped with the bendable area, of an orthographic projection of the first support area on the display substrate.
