Patent ID: 8334527

Claim:
An electroluminescent device comprising: a first electrode layer; a second electrode layer situated opposite to the first electrode layer; and a luminescent layer situated between the first electrode layer and the second electrode layer, wherein the luminescent layer has a quantum dot, and situated around the quantum dot is a silane coupling agent, wherein the luminescent layer includes a hydrolysate-condensation product of the silane coupling agent to get hardened, and wherein the hydrolysate-condensation product of the silane coupling agent is an organopolysiloxane that is a hydrolysate- or co-hydrolysate-condensation product of one, or two or more silicon compounds having the formula Y n SiX (4-n) , in which: Y represents a functional group bound to a silicon atom via a vinyl group or a phenyl group, the functional group having at least one of the property of transporting holes and the property of transporting electrons, X represents an alkoxyl group, an acetyl group, or a halogen; and n is either 2 or 3.
