The display device includes an anti-reflection film having a plurality of projections over a display screen surface and a protective layer filling a space between the projections. The number of times of incidence of external light entering the display device on the anti-reflection film is increased; therefore, the amount of external light transmitted through the anti-reflection film is increased. Thus, the amount of external light reflected to a viewer side is reduced, and the cause of a reduction in visibility such as reflection can be eliminated. Further, since the plurality of projections is covered with a protective layer, entry of dust can be prevented, and physical strength of the anti-reflection film can be increased.
