Title:
INK AND LIGHT-EMITTING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2019/065435
Kind Code:
A1
Abstract:
Provided are: an ink capable of preventing a reduction in light emission efficiency caused by a self-absorption phenomenon; and a light-emitting element having high light emission efficiency. This ink comprises: particles constituted by light-emitting semiconductor nanocrystals and a dispersing agent supported by the semiconductor nanocrystals; a first dispersion medium including an aromatic ring or a methylene group directly bonded to a hetero atom; and a second dispersion medium different from the first dispersion medium. The ink is characterized in that the amount of the first dispersion medium included in the ink is from 20 to 50 mass%.
