Colour film sheet and fabricating method therefor, colour film substrate, and display apparatus

A method for manufacturing a color filter, comprising:

• mixing a plurality of first quantum dots into a first organic solvent to form a first light emitting layer material;
• using the first light emitting layer material to form a first quantum dot light emitting layer, wherein the first quantum dot light emitting layer has a light incident surface, and the first quantum dots are configured to be stimulated by light of a first wavelength to emit light of a second wavelength;
• forming a first reflective layer on a side of the first quantum dot light emitting layer away from the light incident surface, wherein the first reflective layer is configured to transmit the light of the second wavelength and reflect the light of the first wavelength;
• mixing a plurality of second quantum dots and a plurality of light absorbing materials into a second organic solvent to form a second light emitting layer material, wherein the second quantum dots are configured to be stimulated by light of the first wavelength to emit light of the second wavelength, and the light absorbing materials are configured to absorb the light of the first wavelength;
• and
• using the second light emitting layer material to form a second quantum dot light emitting layer between the first quantum dot light emitting layer and the first reflective layer,
• wherein the first quantum dots and the second quantum dots are both stimulated by light of the first wavelength to emit light of the second wavelength.
