ABSTRACT:
A light-emitting device is provided which uses an encapsulant material made from a polymer having a high relative light output. The light-emitting device includes a light-emitting element and a member sealing the light-emitting element. The encapsulant material has one or more than two kinds of units given by the following formula (1) and a refractive index of 1.55 or more.where R is a hydrogen atom, alkyl group or phenyl group, Y is an alkyl group of which the carbon number is 1 to 6 or an alkyloxy group of which the carbon number is 1 to 6 and Z is an aromatic compound that meets predetermined requirements.
