An object of the present invention is to provide a light emitting layer forming ink composition having excellent productivity and discharge stability in a droplet discharge method (inkjet method), and a light emitting device having high light emission efficiency and durability using the ink composition. And an electroluminescence device having the same and excellent in toning properties. A light emitting layer forming ink composition used for forming a light emitting layer constituting a light emitting element by a droplet discharge method, comprising a quantum dot and a host compound, and further having a boiling point of 180 to 320. Solvent A in the range of 10 ° C. within the range of 10 to 90% by mass of the total amount of solvent, and the solvent B having a boiling point in the range of 60 ° C. or higher and lower than 180 ° C. An ink composition for forming a light emitting layer, which is contained within a range of mass%. [Selection figure] None |
