1. A manufacturing method of a modular structure for a display device, comprising:
providing a curved cover plate;
providing a polarizing structure, wherein the polarizing structure comprises:
a support film, comprising a first bonding side and a second bonding side disposed oppositely to each other in a thickness direction of the support film, wherein the first bonding side is capable of being bonded to the curved cover plate; and
a polarizer, bonded on the second bonding side of the support film,
wherein an outer contour of an orthographic projection of the support film on a reference plane is located outside an outer contour of an orthographic projection of the polarizer on the reference plane, and a minimum distance between the outer contour of the orthographic projection of the support film on the reference plane and the outer contour of the orthographic projection of the polarizer on the reference plane is greater than 0.5 mm, where the reference plane is a plane perpendicular to the thickness direction;
bonding the first bonding side of the support film in the polarizing structure to the curved cover plate; and
cutting the support film along a cutting line, wherein in a plane extending along the thickness direction of the support film, an end of the cutting line extends inwards with relative to an end of an outer contour of the support film, and extends outward with relative to an end of an outer contour of the polarizer,
wherein after cutting the support film along the cutting line, in the plane extending along the thickness direction of the support film, the end of the outer contour of the support film extends outward with relative to the end of the outer contour of the polarizer by a minimum distance ranging from 0.1 mm to 0.5 mm.
