Abstract: The present disclosure relates to the field of display and, in particular, to a polarizing structure, a modular structure, and a manufacturing method thereof. The polarizing structure includes a support film having first and second bonding sides disposed oppositely in the thickness direction thereof, wherein the first bonding side can be bonded to the curved cover plate, and a polarizer bonded on the second bonding side of the support film. An outer contour of the orthographic projection of the support film on a reference plane is located outside the outer contour of the orthographic projection of the polarizer on the reference plane. The minimum distance between the outer contours of the orthographic projections of the support film and the polarizer on the reference plane may be, for example, greater than 0.5 mm. The reference plane is a plane perpendicular to the thickness direction.
