Claim 0:
1. A display panel, comprising:
a display region and a frame region, wherein in the frame region, the display panel comprises:
a base substrate comprising a first organic base substrate, a second organic base substrate, and an inorganic base substrate disposed between the first organic base substrate and the second organic base substrate;
a first inorganic layer formed on the second organic base substrate;
a second inorganic layer formed on the first inorganic layer;
an encapsulation layer formed directly on the first inorganic layer and the second inorganic layer; and
at least one groove passing through both the first inorganic layer and the second organic base substrate, wherein each of the at least one groove comprises a first groove portion passing through the first inorganic layer and a second groove portion passing through the second organic base substrate, a bottom surface of the second groove portion coincides with a top surface of the inorganic base substrate, and an orthographic projection of the first groove portion projected on the first organic base substrate falls within an orthographic projection of the second groove portion projected on the first organic base substrate and is less than an area of the orthographic projection of the second groove portion projected on the first organic base substrate;
wherein the encapsulation layer contacts with the second inorganic layer; and
wherein the encapsulation layer is disconnected at each of the at least one groove.
