Claim 7:
8. A display device, comprising:
an array substrate including a first surface and a second surface configured to correspond to the first surface; and
a color filter substrate including a third surface and a fourth surface configured to correspond to the third surface, wherein the second surface is aligned with and attached to the fourth surface;
wherein the color filter substrate includes a color filter layer, and a material of the color filter layer includes a dye, a polymer resin, a monomer, a photoinitiator, and a solvent;
wherein a material of the dye is one of a core-shell material or a titanium dioxide material, the shell material includes an organic polymer, and the core material is an inorganic fluorescent material;
wherein the shell material covers the core material, and the inorganic fluorescent material includes a europium-doped compound; and
wherein the color filter layer includes a first light conversion portion, a second light conversion portion, and a light diffusion portion repeatedly arranged in sequence, the first light conversion portion is one of a red light conversion material or a green light conversion material, the second light conversion portion is the other one of the red light conversion material or the green light conversion material, the light diffusion portion is the titanium dioxide material, and the red light conversion material and the green light conversion material are the inorganic fluorescent material.
