Claim Text:
1. A light emitting device, comprising: a substrate; a resin package disposed on the substrate, the resin package comprising a light-reflective resin; a light emitting element that is laterally surrounded by the resin package such that the resin package contacts lateral surfaces of the light emitting element; a phosphor-containing layer containing at least one kind of phosphor; and a bandpass filter disposed between the phosphor-containing layer and the light emitting element, wherein the bandpass filter is laterally surrounded by the resin package such that the resin package contacts lateral surfaces of the bandpass filter, and wherein the bandpass filter comprises a multilayer film including a plurality of first and second dielectric layers, the second dielectric layer being disposed over the first dielectric layer, wherein the bandpass filter has a transmittance of 60% or more for light having a light emission peak wavelength of the light emitting element at an incident angle in a range of 0 to 85° , and wherein the bandpass filter has a transmittance of 40% or less for light having a light emission peak wavelength of the at least one kind of phosphor at an incident angle in a range of a Brewster's angle (θ
