Display panel, method for fabricating the same, and display device

A display panel, comprising:

• a first base substrate comprising a second base substrate and a third base substrate, wherein a thickness of the second base substrate is smaller than a thickness of the third base substrate;
• and
• an anode layer, a light-emitting layer, a cathode layer, and an encapsulation layer arranged successively on the third base substrate, wherein the cathode layer and the encapsulation layer are arranged on the second base substrate;
• wherein at least one installation hole for installing a hardware structure is arranged in the display panel, a display area surrounds the blind hole area, and the at least one installation hole runs through the first base substrate and respective layers on the first base substrate in a direction perpendicular to the first base substrate;
• wherein the encapsulation layer on the second base substrate and the encapsulation layer on the third base substrate are continuous, and the encapsulation layer covers the respective layers on the second base substrate and the third base substrate.
