[0119] Manufacturing example 1: Synthesis of green quantum dots A-1 with CdSe (core) / ZnS (shell) structure
[0120] CdO (0.4 mmol), zinc acetate (4 mmol), oleic acid (5.5 mL) and 1-octadecene (20 mL) were put into a reactor, and heated at 150° C. for reaction. Afterwards, in order to remove the acetic acid produced by the substitution of zinc with oleic acid, the aforementioned reactants were placed under a vacuum of 100 mTorr for 20 minutes.
[0121] After that, after heating to 310° C. to obtain a transparent mixture, which was maintained at 310° C. for 20 minutes, 0.4 mmol of Se powder and 2.3 mmol of S powder were dissolved in 3 mL of trioctylphosphine (trioctylphosphine) of Se and S solution is quickly injected into the Cd(OA) 2 (Cadmium oleate) and Zn(OA) 2 (Zinc oleate) solution in the reactor. The mixture thus obtained was grown at 310° C. for 5 minutes, and then the growth was stopped in an ice bath.

[0123] Production Example 2: Synthesis of Alkali-Soluble Resin
[0124] Prepare a flask with a stirrer, a thermometer, a reflux condenser, a dropping funnel, and a nitrogen gas introduction tube. On the other hand, add 45 parts by weight of N-benzylmaleimide, 45 parts by weight of methacrylic acid, 10 parts by weight of Tricyclodecanyl methacrylate, 4 parts by weight of tert-butyl peroxy-2-ethylhexanoate, and 40 parts by weight of propylene glycol monomethyl ether acetate (hereinafter referred to as "PGMEA") were stirred and mixed On the other hand, a monomer dropping funnel was prepared, and 6 parts by weight of n-dodecyl glycol and 24 parts by weight of PGMEA were added and stirred to prepare a chain transfer agent dropping funnel.
[0125] Thereafter, 395 parts by weight of PGMEA were introduced into the flask, and the atmosphere in the flask was changed from air to nitrogen, and then the temperature of the flask was raised to 90° C. while stirring.
[0126] Next, the mono...

[0128] Examples 1-16 and Comparative Examples 1-6: Manufacture of a single-layer color filter
[0129] As described in the following Tables 1 to 4, each component was mixed separately, diluted with propylene glycol monomethyl ether acetate until the total solid content was 20% by weight, and fully stirred to obtain a self-luminous photosensitive resin composition. Table 1 shows the types of scattering particles used in Examples and Comparative Examples. In addition, Table 2 shows the use of scattering particles TiO 2 The composition of the examples, Table 3 shows the use of Al 2 o 3 Examples of and TiO 2 The composition of the examples with different content. On this basis, Table 4 shows the compositions used in Comparative Examples.
