1. a method for making for quantum dot color membrane substrates, is characterized in that, comprises the following steps:

  • Step 1, provide a underlay substrate (11), one deck black photoresist layer (12) is formed in the upper coating of described underlay substrate (11), vacuum drying and prebake conditions are carried out to described black photoresist layer (12), to remove the partial solvent in described black photoresist layer (12);

    Step 2, coating formation layer of transparent photoresist layer (13) on described black photoresist layer (12);

    Step 3, provide mask plate (50), described mask plate (50) has first, second, third figure (51,52,53) of several different gray scale, adopt ultraviolet light to be exposed described transparent photomask glue-line (13) by mask plate (50);

    Step 4, developing manufacture process is carried out to described black photoresist layer (12) and transparent photomask glue-line (13), obtain several the transparent barricades (131) of described first figure (51) of correspondence belonging to described transparent photomask glue-line (13), corresponding described second graph (52) and the several auxiliary compartment partings (132) be positioned on described transparent barricade (131), and corresponding described 3rd figure (53) and the several primary divider (133) be positioned on described transparent barricade (131), obtain belonging to simultaneously described black photoresist layer (12) several black barricades (121) of covering by several transparent barricades (131) described,Wherein, the height of described primary divider (133) is greater than the height of described auxiliary compartment parting (132);

    Several black barricades (121) described and on several transparent barricades (131) form several pixel barricades (100), described underlay substrate (11) crosses several red subpixel areas, several green subpixel areas and several blue subpixel areas;

    Step 5, described black barricade (121), transparent barricade (131), auxiliary compartment parting (132) and primary divider (133) to be toasted, with removing wherein most of solvent, strengthen its state of cure and adhesion;

    Step 6, the mode of inkjet printing is adopted to form patterned redness, green and blue quantum dot layer (141,142,143) respectively in the upper corresponding described redness of described underlay substrate (11), green and blue subpixel areas.
