Abstract: Disclosed are a display panel, a manufacturing method therefor, and a display device. The the display panel includes a substrate; a signal shielding layer, disposed on the substrate; a protection layer, disposed on the signal shielding layer; an isolation structure, disposed on the signal shielding layer and defined with a plurality of first isolation openings and a plurality of second isolation openings; and a light-emitting function layer, including a plurality of light-emitting devices. Orthogonal projections of the signal shielding layer and the protection layer on the substrate cover an orthogonal projection of the second isolation opening on the substrate separately. An area of the second isolation opening may serve as a light transmission hole area; and the signal shielding layer may effectively shield interference of a touch signal. Meanwhile, the signal shielding layer may be protected by the protection layer from damage thereby avoiding shielding failure and improving touch performance.
