More Information
Summary:One embodiment provides an ink composition including a mixed solvent including a first solvent and a second solvent, and a light-emitting material, wherein the first solvent and the second solvent each has a vapor pressure of 1 x 10^-4 or more and a boiling point of 270℃ or less. The ink composition of one embodiment can be applied to form a light-emitting layer of a light-emitting device to provide a light-emitting device with improved efficiency. 일 실시예는 제1 용매 및 제2 용매를 포함하는 혼합 용매 및 발광 재료를 포함하고, 제1 용매 및 제2 용매는 각각 증기압이 1x10-4 이상이고, 비점이 270℃ 이하인 잉크 조성물을 제공한다. 일 실시예의 잉크 조성물은 발광 소자의 발광층 형성에 적용되어 효율이 향상된 발광 소자를 제공할 수 있다.
