The method for manufacturing a quantum dot color filter of the present invention, after forming a blue sub-pixel part of a quantum dot color filter by applying a photolithographic operation to a transparent organic photoresist material, applies hydrophobicity treatment to the transparent organic photoresist layer so as to make use of hydrophobic characteristics so formed to help coat green quantum dot curable paste and red quantum dot photoresist sequentially on corresponding areas to form, in sequence, a green quantum dot curable paste layer and a red quantum dot photoresist layer located thereon, and then applies photolithographic operations to subject portions of the red quantum dot photoresist layer to etching for forming a green sub-pixel part and a red sub-pixel part of the quantum dot color filter, whereby compared to the conventional ways of manufacturing a quantum dot color filter, at least one round of photolithographic operation can be saved to greatly simplify the manufacturing process, reduce cost, and improve manufacturing efficiency, and it only needs to develop one type of quantum dot photoresist so as to greatly reduce difficulty and cost of development."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for manufacturing quantum dot color filter","description":"The present invention provides a method for manufacturing a quantum dot color filter.
