A display comprising plural pixels, wherein each of the pixels includes a first sub-pixel, a second sub-pixel, and a third sub-pixel, each of the sub-pixels includes a concavo-convex region (111, 121, 131) on a reflective surface on which incident light is reflected, wherein plural protrusions or recesses are arranged irregularly in the concavo-convex region, in the first sub-pixel, the plural protrusions or recesses arranged in the concavo-convex region each have a first height or depth configured to display a first color, wherein the saturation of the first color is adjustable by an area ratio of the concavo-convex region in the first sub-pixel, in the second sub-pixel, the plural protrusions or recesses arranged in the concavo-convex region each have a second height or depth configured to display a second color, wherein the saturation of the second color is adjustable by an area ratio of the concavo-convex region in the second sub-pixel and in the third sub-pixel, the plural protrusions or recesses arranged in the concavo-convex region each have a third height or depth configured to display a third color, wherein the saturation of the third color is adjustable by an area ratio of the concavo-convex region in the third sub-pixel, wherein the length of a long side and a short side of the plural protrusions or recesses is 0.5 μm or more and 50 μm or less, the height of the protrusions or the depth of the recesses is 0.05 μm or more and 0.5 μm or less, and the center-to-center distance between adjacent ones of the protrusions or recesses in each of the sub-pixels is 0.6 μm or more and 110 μm or less on average. each of the pixels includes a first sub-pixel, a second sub-pixel, and a third sub-pixel, each of the sub-pixels includes a concavo-convex region (111, 121, 131) on a reflective surface on which incident light is reflected, wherein plural protrusions or recesses are arranged irregularly in the concavo-convex region, in the first sub-pixel, the plural protrusions or recesses arranged in the concavo-convex region each have a first height or depth configured to display a first color, wherein the saturation of the first color is adjustable by an area ratio of the concavo-convex region in the first sub-pixel, in the second sub-pixel, the plural protrusions or recesses arranged in the concavo-convex region each have a second height or depth configured to display a second color, wherein the saturation of the second color is adjustable by an area ratio of the concavo-convex region in the second sub-pixel and in the third sub-pixel, the plural protrusions or recesses arranged in the concavo-convex region each have a third height or depth configured to display a third color, wherein the saturation of the third color is adjustable by an area ratio of the concavo-convex region in the third sub-pixel, wherein the length of a long side and a short side of the plural protrusions or recesses is 0.5 μm or more and 50 μm or less, the height of the protrusions or the depth of the recesses is 0.05 μm or more and 0.5 μm or less, and the center-to-center distance between adjacent ones of the protrusions or recesses in each of the sub-pixels is 0.6 μm or more and 110 μm or less on average.
