Abstract: Disclosed are a light-emitting substrate and a display device. In the light-emitting substrate, a first pad of a light-emitting area includes a first metal layer located above a base substrate and a second metal layer located on a side, facing away from the base substrate, of the first metal layer. A material of the second metal layer includes copper-nickel-titanium alloy, and a quantity of nickel atoms and/or titanium atoms contained per unit area in a cross section, farther from the base substrate, of the second metal layer is greater than a quantity of nickel atoms and/or titanium atoms contained per unit area in another cross section, closer to the base substrate, of the second metal layer.
