Abstract
A display device includes a first display unit and a second display unit. The first display unit emits a first output light having a first output spectrum corresponding to a highest gray level of the display device. The second display unit emits a second output light having a second output spectrum corresponding to the highest gray level of the display device. Wherein, a mixed output spectrum is a mixture spectrum of the first output spectrum and the second output spectrum, a maximum peak of the first output spectrum from 507 nm to 555 nm is defined as a first peak corresponding to a first wavelength, a maximum peak of the mixed output spectrum from 507 nm to 555 nm is defined as a mixed peak corresponding to a mixture wavelength, and the first wavelength is different from the mixture wavelength.
