Abstract
The present invention discloses a display device and a manufacturing method thereof having a light emission backplate, color conversion layer and a color film layer. The color conversion layer includes a red light conversion unit, a green light conversion unit, and an opening unit. The red light conversion unit and/or green light conversion unit includes calcium titanate light emitting material and scattering particles stacked in the calcium titanate light emitting material. In a vertical direction pointing from a surface of the color conversion layer near the light emission backplate to a surface away from the light emission backplate, a refractive index of the scattering particles gradually increases.
