[0036] It is believed that selecting a polar ligand as the chemical compound when the ligand directly attached onto the light-emitting portion is a non-polar ligand, and selecting a non-polar ligand as the chemical compound when the ligand of the light-emitting portion is a polar type ligand, reduces the polarity difference between the light-emitting portion of the composition and the reactive monomer / monomer mixture of two or more reactive monomers, resulting in better dispersibility of the light-emitting portion, improved external quantum efficiency (EQE) values ​​of the composition and layers obtained from the composition, and / or improved ink jetting properties.

(The incorporation ratio of oleic acid compared to mPEG-SH is 55%.) The solvents are PGMEA, LA, HDDA, and LA+HDDA.

[0166] Example 9: Calculation of Hansen Solubility Parameters (HSP) for QDs with non-polar ligands, QDs with polar ligands, and solvents The HSPs (δD, δP, δH) of the molecules are calculated by the HSPiP software (pirica.com). The HSP of heptane is used for QDs with nonpolar ligands because the -SH, -COOH moieties in the nonpolar ligands are attached onto the QD surface. The HSP of poly(ethylene glycol) dimethyl ether is used for QDs bearing polar ligands because the -SH moieties in DDT are attached onto the QD surface. The HSP of the mixed solvents is determined by the following addition rules:

[0168] Comparative Example 2: Preparation of red QD ink containing QDs with DDT ligands [Table E]

[0169] Example 11: Preparation of red QD ink containing QDs with dodecanoic acid ligands along with mPEG350SH The incorporation ratio of mPEG350SH compared to dodecanoic acid is 103%. [Table F]

[0172] result Table 1 shows the results of DLS measurements for Example 6. Table 2 shows the results of DLS measurements for Example 7. By adding polar ligands to the QD ink solution containing QDs with non-polar ligands & reactive monomers, the cumulant size of the QDs is controlled, and the small cumulant size QDs do not show QD aggregation and are well dispersed. Adding both non-polar and polar ligands to the QD ink solution also controls the size of the QDs in the reactive monomers.

[0175] Table 3 shows the results of DLS measurements of Example 8. By adding non-polar ligands to the QD ink solution containing QDs with polar ligands & reactive monomers, the cumulant size of the QDs is controlled, and the small cumulant size QDs do not show QD aggregation and disperse well in the reactive monomers. Table 3 [Table 3-1] [Table 3-2]

[0176] Table 4 shows the results of the HSP calculation of Example 8. δD is the dispersion force. δP is the polar force. δH is the hydrogen bond force. By mixing polar and non-polar ligands, the HSP can be controlled to be close to the HSP of the reactive monomer. A close HSP between the QDs and the reactive monomer is necessary for a well-dispersed sample. Table 4 [Table 4] The red QD inks of Examples 10, 11, and 12 show superior dispersibility compared to Comparative Examples 2 and 3.
