Abstract: Phosphors or quantum dots cannot convert all the excitation lights, but the remaining excitation lights have to be absorbed with a color filter without passing through. A display device includes an array substrate having a color layer and an opposite substrate. The color layer includes a red fluorescence layer for converting blue light into red, a green fluorescence layer for converting blue light into green, and a blue fluorescence layer for compensating blue light. Both of the red fluorescence layer and the green fluorescence layer include the phosphors or quantum dots with two types of dominant wavelengths. The blue fluorescence layer includes the phosphors or quantum dots with one type of dominant wavelength.
