Abstract

A display panel and a fabricating method thereof, and a displaying device. The display panel includes: a driving backplane, a light-emitting-device layer provided on the driving backplane, and a packaging layer, a color-film layer and a light absorbing layer provided on one side of the light-emitting-device layer that is further away from the driving backplane; wherein the light absorbing layer is configured for absorbing light rays of a specific wavelength in external-environment light and in light rays emitted by the light-emitting-device layer; and the specific wavelength includes at least one of a wavelength between a red-light wave band and a green-light wave band, a wavelength between a green-light wave band and a blue-light wave band, a wavelength shorter than a blue-light wave band and a wavelength longer than a red-light wave band.
