fixedly arranging the chip on film on one side of the display panel, which is provided with the first binding gasket, and enabling the second binding gasket to be positioned on one side of the chip on film, which is far away from the display panel;
forming a connecting structure connecting the first and second binding pads;
forming a planarization layer on one side of the first binding gasket and the second binding gasket, which is far away from the display panel, wherein the planarization layer covers the connecting structure and at least part of the chip on film;
and forming a support plate on one side of the planarization layer, which is far away from the display panel.
9. The method according to claim 8, wherein before forming a support plate on a side of the planarization layer facing away from the display panel, the method further comprises:
and a back plate is formed on one side of the planarization layer, which is far away from the display panel, and the support plate is formed on one side of the back plate, which is far away from the planarization layer.
10. The method for manufacturing a display device according to claim 8, wherein the display device further comprises:
providing a flexible circuit board and an integrated circuit chip;
electrically connecting the flexible wiring board and the integrated circuit chip to the chip on film.
