Abstract: A preparation method of a color film layer, a display substrate and a preparation method thereof. The display substrate includes a bearing layer and repeating units, each repeating unit including a green film layer, a red film layer and a blue film layer, which are provided on the bearing layer and directly contacting a first surface of the bearing layer. On a plane parallel to the first surface of the bearing layer, in each repeating unit, the red film layer is provided on a first side of the green film layer, the blue film layer is provided on a second side of the green film layer opposite to the first side; one of the red film layer and the blue color film layer covers part of the green film layer; one part of the green film layer does not overlap with the red film layer and the blue film layer.

Abstract: Disclosed are a display panel, a manufacturing method thereof, and a display device. The display panel includes a base substrate and sub-pixels thereon. At least one sub-pixel includes: a light emitting element including a first electrode, a luminous functional layer and a second electrode sequentially stacked, the first electrode being closer to the base substrate than the second electrode; a metal reflective layer, between the base substrate and the first electrode; a silicon nitride layer, between the first electrode and the metal reflective layer, and including a first via hole through which the first electrode is connected with the metal reflective layer; a driving circuit including a driving transistor and a storage capacitor between the base substrate and the metal reflective layer, the driving transistor including a gate electrode connected with the storage capacitor, and source and drain electrodes, one of which is connected with the metal reflective layer.
