A laminating apparatus for laminating an object to be laminated includes: a rigid substrate, and a jig provided on a side of the rigid substrate and in contact therewith. The jig is of an elastic material, and a surface of the jig away from the rigid substrate is a first surface. A horizontal plane at any point in a surface of the rigid substrate away from the jig is a first reference plane, and a contact interface between the rigid substrate and the jig is a second surface. For any one of the at least one segment of cambered surface, a distance between the second surface and the first reference plane increases as a non-obtuse angle between a tangent of the first surface and the horizontal direction increases.
