Abstract: A resin composition, a light conversion layer and a light emitting device are provided. The resin composition includes a quantum dot (A), an alkali-soluble resin (B), an ethylenically unsaturated monomer (C), a photoinitiator (D), a solvent (E) and a phenyl-based compound (F). The phenyl-based compound (F) includes at least one of a compound represented by following Formula (F-1) and a compound represented by following Formula (F-2). Based on a total usage amount of the resin composition as 100 parts by weight, a usage amount of the phenyl-based compound (F) is 0.05 to 5 parts by weight. In Formula (F-1) and Formula (F-2), the definition of R1, R3, R4, Y, Z, m, n and p are the same as defined in the detailed description.

Abstract: An ink composition, a light conversion layer and a light emitting device are provided. The resin composition includes a quantum dot (A), a first resin (B1), a second resin (B2), an ethylenically unsaturated monomer (C), an initiator (D) and a solvent (E). The first resin (B1) is an alkali-insoluble resin, and the second resin (B2) is an alkali-soluble resin. The first resin (B1) includes a compound represented by the following Formula (1): In Formula (1), n is an integer from 1 to 10, X is benzene, toluene or naphthalene, and Y is toluene, methylnaphthalene, tetrahydrodicyclopentadiene, or 4,4′-dimethyl-1,1′-biphenyl.
