Display Panel and Manufacturing Method Thereof, and Display Device

Provided are a display panel and a manufacturing method thereof, and a display device. The display panel includes: a base substrate including a display area and a peripheral area; sub-pixels located, at least one sub-pixel including a driving transistor including conductive layers; a first dam located at the peripheral area; a second dam located at the peripheral area and located on one side of the first dam away from the display area; an encapsulation layer, orthographic projections of the sub-pixels, the first and the second dam on the base substrate being located within that of the encapsulation layer; and at least one pressure sensor located on at least one of a first side of the second dam proximate to the first dam or a second side away from the first dam, wherein at least one resistor in each pressure sensor is located in a same layer as one conductive layer.
