Abstract
A display device and a method of manufacturing the same are provided. The display device includes an illuminate unit and a color filter. The illuminate unit has a light-emitting chip and a plurality of quantum dot phosphors for generating a color light which has an optical spectrum including the first blue peak wavelength, a first green peak wavelength, and a first red peak wavelength. The color filter is disposed in the light path of the color light, wherein the color filter has a transmittance spectrum having a second blue peak wavelength, a second green peak wavelength, and a second red peak wavelength. The first blue peak wavelength, the first green peak wavelength, and the first red peak wavelength respectively match the second blue peak wavelength, the second green peak wavelength, and the second red peak wavelength in order to enhance the color performance of the display device.
