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.

Abstract: A display device is disclosed. The display device includes a display panel, and a grating layer arranged inside or outside of the display panel. Along a direction pointing from a center of a sight concentration area of the display device to a non-sight concentration area of the display device, a grating period of the grating layer decreases gradually. When incident light incident on the grating layer is diffracted at an area of the grating layer corresponding to the non-sight concentration area of the display device, the obtained light of non-zero order diffraction falls into a sight of a viewer.
