Claim 18:
19. The display device manufacturing method as claimed in claim 18, wherein the scattering particles at least comprise first scattering particles and second scattering particles, and a refractive index of the first scattering particles is less than a refractive index of the second scattering particles, the step B comprises:
mixing the first scattering particles and second scattering particles with the calcium titanate light emitting material respectively;
coating a first mixture including the first scattering particles and the calcium titanate light emitting material on the light emission backplate; and
coating a second mixture including the second scattering particles and the calcium titanate light emitting material on the first mixture to form the red light conversion unit and/or the green light conversion unit.
