Display panel, fabrication method of display panel, and display device

A display panel, comprising:

• a substrate;
• an insulating layer arranged at one side of the substrate;
• a conductive adhesive layer arranged at one side of the insulating layer away from the substrate and including at least an edge portion extending along a top surface of the insulating layer at the one side;
• and
• a chip arranged at one side of the conductive adhesive layer away from the substrate;
• wherein:
• the insulating layer is provided with an accommodation groove, and first electrodes are arranged within the accommodation groove;
• along a direction perpendicular to a plane where the substrate is located, an orthographic projection of the conductive adhesive layer on the substrate covers an orthographic projection of the accommodation groove on the substrate;
• part of the conductive adhesive layer is in contact with the first electrodes, and the chip is in contact with the conductive adhesive layer;
• a gas releasing channel is provided in the insulating layer for the accommodation groove to communicate with outside;
• the substrate includes a first surface, the first electrodes being arranged at the first surface;
• the insulating layer includes a second surface and a side surface, the second surface being parallel to the first surface, and the side surface connecting the first surface and the second surface;
• and
• the channel includes an inlet and an outlet, the inlet being arranged at the side surface, and the whole outlet being arranged at the second surface at a position not covered by the chip.
