Disclosed are a touch display panel and a manufacturing method therefor, and a display apparatus. A problem of high cost and a thick thickness of a touch display apparatus is solved. The touch display panel includes: a substrate; an isolation structure layer with a plurality of isolation openings; a plurality of light-emitting devices located in the isolation openings, the light-emitting device including a first electrode facing the substrate; and a touch electrode including a first touch electrode and a second touch electrode. The second touch electrode includes a plurality of main body portions and a plurality of bridge portions disposed in different layers. The first touch electrode, the plurality of main body portions and the first electrode are disposed in a same layer; or the first touch electrode, the plurality of main body portions and the isolation structure layer are disposed in a same layer.
