Abstract
A light emitting device is configured to include a substrate and a luminous layer provided overlying the substrate, which includes a semiconductor nanocrystal to which a carbazole derivative is coordination-bonded or attached, the carbazole derivative having aromatic rings of a compound represented by the chemical structure 1, which is substituted by one to three substitution groups:The one to three substitution groups are represented by the chemical structure 2:-X-Y-Z Chemical Structure 2.X represents a methylene group, a carbonyloxy group, an oxycarbonyl group, a carbonyl group, an oxygen atom, and a sulfur atom, Y represents a substituted or non-substituted alkylene group, and Z represents a carboxyl group, a hydroxyl group, and a thiol group.
