A display panel includes a substrate. A color film layer is formed on the substrate. The color film layer includes first color resistances and second color resistances, first color quantum dots are disposed in the first color resistances, and second color quantum dots are disposed in the second color resistances. The color film layer further includes reflecting color resistances, the reflecting color resistances are formed between the first color resistances and the second color resistances. Reflectivities of contact surfaces between the reflecting color resistances and the first color resistances and between the reflecting color resistances and the second color resistances are greater than 70%, to make first color incident light emitted by the quantum dots of the first color resistances and second color incident light emitted by the quantum dots of the second color resistances to be reflected back to color resistances to excite the quantum dots to illuminate.
