Abstract: A display substrate and a manufacturing method thereof, and a display panel are provided. The display substrate includes at least one set of signal lines and at least one shielding structure disposed on a base substrate. The shielding structure is electrically connected to a DC power source. The shielding structure includes a shielding portion. Each set of signal lines includes a first signal line and a second signal line at different layers. Orthographic projections of first signal line and second signal line on base substrate overlap and have an overlapping region. Shielding portion is located between the first signal line and the second signal line, and insulated from the two signal lines. An orthographic projection of the shielding portion on base substrate at least partially overlaps the overlapping region. Since voltage on shielding structures is stable, thereby effectively avoiding crosstalk between the two signal lines in set of signal lines.

Abstract: A top-emitting organic electroluminescent display panel, a manufacturing method, and a display device. The top-emitting organic electroluminescent display panel comprises: a substrate, a layer of white organic light emitting diodes and a thin film encapsulation layer arranged on the substrate in sequence. The thin film encapsulation layer comprises at least two inorganic thin film layers and at least one organic thin film layer. At least one organic thin film layer is a color filter layer, the color filter layer being arranged between the at least two inorganic thin film layers. Since one of the organic thin film layers in the thin film encapsulation layer is a color filter layer, the color filter layer does not have to be arranged above the thin film encapsulation layer separately, thus reducing the number of film layers, simplifying the film layer structure, reducing manufacturing costs, and improving the luminous efficiency and the display effect.
