Abstract
The disclosure provides a display device, including a display unit emitting an output light having an output spectrum corresponding to a highest gray level of the display device. A maximum peak of the output spectrum from 543 nm to 780 nm is defined as an intensity peak corresponding to a wavelength, an intensity integral of the output spectrum from the first wavelength to 780 nm is defined as a first intensity integral, and an intensity integral of the output spectrum from 543 nm to the first wavelength is defined as a second intensity integral. A ratio of an intensity integral of the output spectrum from 380 nm to 543 nm to a sum of the first intensity integral and the second intensity integral is greater than or equal to 0.05% and less than or equal to 4.00%.
