Abstract
A display device includes a first display unit and a second display unit. The first display unit emits a green light having a first output spectrum corresponding to a highest gray level of the display device. The second display unit emits a blue light having a second output spectrum corresponding to the highest gray level of the display device. Wherein, an intensity integral of the first output spectrum within a range from 380 nm to 780 nm is defined as a first intensity integral, an intensity integral of the second output spectrum within a range from 494 nm to 580 nm is defined as a second intensity integral, a ratio of the second intensity integral to the first intensity integral is defined as a first ratio, and the first ratio is greater than 0% and less than or equal to 26.0%.
