The invention discloses a display device using quantum dot fluorescent powder, which mainly comprises a luminous unit and a color filter. The luminous unit is provided with a luminous chip and multiple quantum dot fluorescent powder and generates colored light, and the emission spectrum is provided with a first blue light peak wavelength, a first green light peak wavelength, and a first red light peak wavelength. The color filter is arranged on a luminous path of the luminous unit, so that the colored light emitted by the display device penetrates the color filter, and the transmission spectrum is provided with a second blue light peak wavelength, a second green light peak wavelength, and a second red light peak wavelength. The first blue light peak wavelength, the first green light peak wavelength and the first red light peak wavelength are respectively matched with the second blue light peak wavelength, the second green light peak wavelength and the second red light peak wavelength so as to improve the expr
