Abstract

A display panel includes a substrate and a grating disposed on a light-emitting side of the display panel. The grating includes a plurality of protruding portions and a plurality of interval portions, each interval portion is located between two adjacent protruding portions. The plurality of protruding portions are arranged on the substrate along a first direction, and each protruding portion extends along a second direction perpendicular to the first direction. Each protruding portion includes an outer surface and a bottom surface; the outer surface is a smooth curved surface, and the bottom surface is a flat surface. A cross-sectional figure of each protruding portion along a thickness direction of the display panel is a first figure; the first figure includes a curve and a bottom edge, and the first figure is a closed figure formed by the curve and the bottom edge. The curve is a cross-sectional figure of the outer surface along the thickness direction of the display panel, and the bottom edge is a cross-sectional figure of the bottom surface along the thickness direction of the display panel.
