In a display device that displays a full-color image, there is a trade-off relationship between brightness and color reproducibility. The display device includes a first white light source including a blue light source and a red phosphor having a composition represented by formula (1) and a green phosphor having a composition represented by formula (2), or a blue light source and A green light source and a second white light source having a red phosphor with a composition represented by formula (1); and a color filter having a red coloring layer disposed on a red pixel and disposed on a green image A green colored layer of the element and a blue colored layer arranged on the blue pixel.
