Disclosed are a display panel and a method of manufacturing a display panel. The display panel includes an array substrate; a color film substrate disposed opposite to the array substrate; a liquid crystal layer disposed between the array substrate and the color film substrate; a reflective layer disposed on a side of the array substrate facing the liquid crystal layer. The reflective layer comprises a plurality of first convex structures, each of the first convex structures has a first sidewall extending from a bottom to a top of each of the first convex structures, and an angle between a normal line of the first sidewall and a horizontal plane is greater than 0° and less than or equal to 10°.
