Claim 17:
18. A display device manufacturing method, comprising steps as follows:
a step A: forming a light emission backplate;
a step B: forming a color conversion layer on the light emission backplate, wherein the color conversion layer is disposed on the light emission backplate, the color conversion layer comprises a red light conversion unit, a green light conversion unit, and an opening unit, the red light conversion unit and/or the green light conversion unit comprises calcium titanate light emitting material and scattering particles stacked and disposed in the calcium titanate light emitting material, a refractive index of the scattering particles gradually increases along a vertical direction pointing from a surface of the color conversion layer near the light emission backplate to a surface of the color conversion layer away from the light emission backplate; and
a step C: forming a color film layer on the color conversion layer, wherein the color film layer is disposed on the color conversion layer, the color film layer comprises a red color resist block, a blue color resist block, and a green color resist block arranged at intervals, wherein the red color resist block, the green color resist block, and the blue color resist block are disposed correspondingly on the red light conversion unit respectively, the green light conversion unit, and the opening unit respectively.
