1. A display panel, comprising a first substrate and a second substrate which are aligned, wherein liquid crystals are filled between the first substrate and the second substrate, the first substrate and the second substrate which are aligned have a display region and a peripheral region surrounding the display region, the peripheral region is provided with a frame sealing adhesive located between the first substrate and the second substrate and surrounding the display region, and the frame sealing adhesive is configured to seal the liquid crystals; and
the peripheral region of the first substrate is provided with a blocking structure located between a region where the frame sealing adhesive is located and the display region and surrounding the display region, and the blocking structure is configured to block the liquid crystals from overflowing an outer side of the frame sealing adhesive away from the display region when the liquid crystals are dripped on the first substrate;
wherein the blocking structure is a protruding structure where a surface of the first substrate corresponding to the peripheral region protrudes out of a surface corresponding to the display region; wherein the first substrate comprises a base substrate, and a plurality of film layers sequentially disposed in a stacked manner on one side of the base substrate facing the liquid crystals, wherein the peripheral region of the first substrate further comprises a first organic insulating layer disposed on one side of any one of the plurality of film layers facing the liquid crystals, the first organic insulating layer is an internal film layer of the protruding structure, and the first organic insulating layer causes the surface of the first substrate corresponding to the peripheral region to protrude out of the surface corresponding to the display region; or
wherein the blocking structure is a closed groove where a surface of the first substrate corresponding to the peripheral region is concave into a surface corresponding to the display region; wherein the first substrate comprises a base substrate, and at least two inorganic insulating layers sequentially disposed in a stacked manner on one side of the base substrate facing the liquid crystals; and at least one of the at least two inorganic insulating layers has a closed through groove at a position where the closed groove is located.
