Abstract: Provided is a display device. The display device includes a display panel and first to third light source units. The display panel includes a plurality of pixels. The first to third light source units are disposed on a rear of the display panel. The first light source unit emits yellow light. The second light source unit emits a first blue light in a first wavelength band. The third light source unit emits a second blue light in a second wavelength band. The second wavelength band includes light of a longer wavelength than light of the first wavelength band. The first wavelength band ranges from about 430 nm to about 455 nm. The second wavelength band may ranges from about 460 nm to about 505 nm.

Abstract: A display device includes a display unit, an upper electrode layer, a lower electrode layer and an electrochromic layer. The display unit includes a plurality of light emitting diodes disposed in a light emitting area. The upper electrode layer is disposed on the display unit, and includes a plurality of first electrode patterns and a plurality of second electrode patterns. The first electrode patterns are arranged in a first direction, and are electrically connected each other. The second electrode patterns are arranged in a second direction intersecting the first direction and are electrically connected each other. The lower electrode layer is disposed between the upper electrode layer and the display unit. The electrochromic layer is disposed between the upper electrode layer and the lower electrode layer, and includes an electrochromic pattern.
