For example, the frame region comprises a first frame region and a second frame region which are opposite to each other in a first direction; the display panel further comprises a flexible circuit board, and the flexible circuit board is connected with the second frame region; and the first frame region is provided with the at least one of the plurality of cover plate alignment marks located between the dam glue and the display region and overlapping with the second inorganic encapsulation layer in the direction perpendicular to the base substrate, and/or the second frame region is provided with the at least one of the plurality of cover plate alignment marks located between the dam glue and the cutting region.
For example, the frame region further comprises a third frame region and a fourth frame region which are opposite to each other in a second direction different from the first direction, and the display panel comprises a curved portion in at least one of the third frame region and the fourth frame region, and a portion of the cover plate corresponding to the curved portion is curved; the display panel further comprises a gate electrode driver in at least one of the third frame region and the fourth frame region; and the plurality of cover plate alignment marks are located outside the third frame region and the fourth frame region.
