Patent ID: 8455905

Claim:
A light-emitting device, comprising: a nitride semiconductor light-emitting element which comprises a light emission surface and which radiates optically polarized light from the light emission surface; and a light emission control layer which covers the light emission surface of the nitride semiconductor light-emitting element and which contains a resin and non-fluorescent particles dispersed in the resin, wherein the light emission control layer contains the non-fluorescent particles at a proportion of 0.01 vol % or more and 10 vol % or less, wherein the non-fluorescent particles have a diameter of 30 nm or more and 150 nm or less, and wherein, when a radiant intensity in an m-axis direction is set as 100% and an angle in the m-axis direction is set as 0°, a difference in radiant intensity between radiant intensity distribution characteristics observed when an a-axis is a rotation axis and an angle range is from −90° to 90° and radiant intensity distribution characteristics observed when a c-axis is the rotation axis and the angle range is from −90° to 90° is 26% points or less at the same angle.
