Claim 11:
12. A method for manufacturing a display panel, comprising: providing an alignment mark region within a flat region of a peripheral region of the display panel,
wherein an alignment mark pattern is arranged within the alignment mark region, and/or at least one film layer within the alignment mark region is hollowed out;
the peripheral region is a region of the display panel other than an active area of the display panel,
wherein the display panel comprises an upper surface, a lower surface, a first side surface, a second side surface, a third side surface and a fourth side surface;
the first side surface, the second side surface, the third side surface and the fourth side surface are curved side surfaces;
an orthogonal projection of the first side surface onto a first plane does not overlap an orthogonal projection of the flat region onto the first plane;
an orthogonal projection of the second side surface onto the first plane does not overlap the orthogonal projection of the flat region onto the first plane;
an orthogonal projection of the third side surface onto the first plane does not overlap the orthogonal projection of the flat region onto the first plane;
an orthogonal projection of the fourth side surface onto the first plane does not overlap the orthogonal projection of the flat region onto the first plane;
the first plane is parallel to the lower surface.
