To achieve a light-emitting device emitting light with high brightness, closer to natural light, and less color shift due to a small change in intensity of emitted light, in a light-emitting device including a light source emitting light by driving current and at least one wavelength-converting material absorbing at least part of the light from the light source and emitting light having a different wavelength, the color coordinate x 1 (17.5) and the color coordinate y 1 (17.5) of the light emitted at a driving current density of 17.5 A/cm 2 and the color coordinate x 1 (70) and the color coordinate y 1 (70) of the light emitted at a driving current density of 70 A/cm 2 satisfy the following Expressions (D) and (E): n −0.006≦ x 1 (17.5)− x 1 (70)≦0.006 (D), n −0.006≦ y 1 (70)− y 1 (70)≦0.006 (E). |
