Beschreibung
Zusammenfassung:	The invention discloses a pressure detector, a preparation method, a display panel and a display device. The pressure detector comprises a substrate; the first electrode plate is arranged on the substrate; the first bonding layer is arranged on one side, far away from the substrate, of the first electrode plate, and the first bonding layer is provided with a first cavity; the second bonding layer is arranged on the side, away from the substrate, of the first bonding layer, and the second electrode plate is arranged on the second bonding layer; orthographic projections of the first electrode plate and the first cavity on the substrate have a first overlapping area, orthographic projections of the second electrode plate and the first cavity on the substrate have a second overlapping area, and at least part of the first overlapping area and at least part of the second overlapping area are overlapped; the orthographic projection of the second bonding layer and/or the second electrode plate on the substrate covers
