  • Publication number: 20210202644
    Abstract: The present disclosure provides an array substrate, a method for fabricating the array substrate, a display panel, and a display device, wherein there is disposed a shielding layer insulated from each of anodes and capable of shielding an electric field between two adjacent pixels, so that when a pixel emits light, an electric field between an anode in the pixel emitting light and an anode in an adjacent pixel can be shielded. Thus, it is possible to avoid a coupling voltage at the anode in the adjacent pixel caused by the anode in the pixel emitting light under the coupling effect, thereby eliminating the interference with the pixel light emission from the coupling effect between the anodes in the two adjacent pixels, and improving the display effect.
