A grating and a manufacturing method therefor, a display substrate and a display device. The grating comprises: a substrate (1), comprising a plurality of first visual field areas (A1) and a plurality of second visual field areas (A2) that are alternately distributed; a plurality of ridge-shaped raised structures (3), formed on the substrate (1) in each first visual field area (A1) and each second visual field area (A2); and a pattern shading layer (2), formed on the ridge-shaped raised structures (3) and comprising a plurality of shading areas and a plurality of transparent areas. Each transparent area is formed on the slope on the first side of each ridge-shaped raised structure (3) in each first visual field area (A1), each transparent area is formed on the slope on the second side of each ridge-shaped raised structure (3) in each second visual field area (A2), and the first side and the second side are two opposite sides. The thickness of the display device using the grating is small. |
