Patent ID: 7928457

Claim:
A semiconductor light-emitting device member, wherein (1) the semiconductor light-emitting device member comprises a functional group capable of forming a hydrogen bond with a hydroxyl group or an oxygen in a metalloxane bond, (2) the maintenance rate of transmittance in a thickness of 1 mm with respect to the light having a wavelength of 400 nm before and after being left at temperature of 200° C. for 500 hours is 80% or more and 110% or less, (3) no change is observed by visual inspection after being irradiated with light having a wavelength range of longer than 385 nm and 500 nm or less, whose center wavelength is located at between 400 nm and 450 nm both inclusive, for 24 hours with illumination intensity of 4500 W/m 2 with respect to the wavelength of 436 nm, and (4) the refractive index with respect to the light having 550 nm wavelength is 1.45 or larger.
