Beschreibung
Zusammenfassung:	The present invention provides a quantum dot solution composition, a quantum dot film formed using the same, and a quantum dot display device, wherein the quantum dot solution composition includes: a solvent; a quantum dot that includes a core, a shell surrounding the core, and a ligand bound to the surface of the shell and has about 0.1 to 20 wt% with respect to the solvent; and an additive that has about 1 to 15 vol% with respect to the solvent and is a phosphine-based compound, and the ligand includes a first ligand that is a carboxylate-based compound and a second ligand that is a phosphine-based compound. 본 발명은, 용매와; 코어와, 상기 코어를 둘러싸는 쉘과, 상기 쉘 표면에 결합된 리간드를 포함하고 상기 용매에 대하여 약 약 0.1~20 중량비(wt%)를 갖는 양자점과; 상기 용매에 대하여 약 약 1~15 부피비(vol%)를 가지며 포스핀계 화합물인 첨가제를 포함하고, 상기 리간드는 카르복실레이트계 화합물인 제 1 리간드와 포스핀계 화합물인 제 2 리간드를 포함하는 양자점 용액 조성물 및 이를 이용하여 형성되는 양자점 필름, 양자점 표시장치를 제공한다.
