Abstract
A displaying base plate and a fabricating method thereof, and a displaying device. The displaying base plate includes: a substrate, and a plurality of displaying units and a plurality of fingerprint identifying units that are located on the substrate; each of the displaying units includes at least one sub-pixel; orthographic projections of the fingerprint identifying units on the substrate are separated from orthographic projections of the displaying units on the substrate; and each of the fingerprint identifying units includes a first electrode and a shielding trace that are insulated from each other, an orthographic projection of the shielding trace on the substrate surrounds at least part of an orthographic projection of the first electrode on the substrate, and the shielding trace is electrically connected to an earthed end of the displaying base plate.
