Claim 4:
5. The display panel according to claim 4, wherein the light-emitting device layer comprises:
a first electrode layer, arranged on the side, facing away from the base substrate, of the pixel circuit layer; wherein the first electrode layer comprises anodes of the active light-emitting devices and the anodes of the passive light-emitting devices;
a pixel defining layer, arranged on one side, facing away from the base substrate, of the first electrode layer; wherein the pixel defining layer has a plurality of openings, and an orthographic projection of one of the openings on the base substrate is arranged in an orthographic projection of one of the anodes on the base substrate;
a light-emitting function layer, arranged on one side, facing away from the base substrate, of the pixel defining layer, wherein an orthographic projection of the light-emitting function layer on the base substrate covers orthographic projections of the plurality of openings on the base substrate; and
a second electrode layer, arranged on one side, facing away from the base substrate, of the light-emitting function layer; wherein the second electrode layer comprises cathodes of the active light-emitting devices and the cathodes of the passive light-emitting devices;
wherein the plurality of isolating strip layers are arranged between the pixel defining layer and the light-emitting function layer, and an orthographic projection of the pixel defining layer on the base substrate covers orthographic projections of the plurality of isolating strip layers on the base substrate; and
the plurality of cathode inhibitor layers are arranged between the light-emitting function layer and the second electrode layer, and the orthographic projection of the pixel defining layer on the base substrate covers orthographic projections of the plurality of cathode inhibitor layers on the base substrate.
