Abstract
A display panel, a display device, and a fabricating method of a display panel. The display panel includes: a base substrate (); a plurality of light-emitting devices () on a side of the base substrate (); and additional members on a side of the light-emitting devices () away from the base substrate (). The additional members includes light extraction structures () and electrochromic structures (), where orthographic projections of the light extraction structures () on the base substrate () overlap orthographic projections of the light-emitting devices () on the base substrate (), and the light extraction structures are configured to draw in light from the light-emitting devices (); and orthographic projections of the electrochromic structures () on the base substrate () are located between orthographic projections of adjacent light-emitting devices () on the base substrate (), and the electrochromic structures are configured such that the electrochromic structures () are in a transparent state when the light-emitting devices () emit light, and electrochromic structures () are in a shading state when the light-emitting devices () do not emit light.
