The invention provides a display panel, a manufacturing method of the display panel, and a display device. The display panel comprises an array substrate and a contraposition substrate which are oppositely arranged, wherein the array substrate comprises a body area and a periphery area, the body area coincides with the orthographic projection of the contraposition substrate on the array substrate, an electrostatic lead-out line and at least one adhesive dispensing area are arranged in the periphery area, conductive adhesives are arranged in the adhesive dispensing areas and electrically connected with grounding parts, an electrostatic conduction structure is arranged on the contraposition substrate, and the conductive adhesives are electrically connected with the electrostatic conduction structure. The display panel leads out static electricity in time through the conductive adhesives, the electrostatic damage can be avoided, and cost can be reduced.
