<p>Provided is a light emitting device which is suppressed in change of color shade caused by a shift of excitation wavelength and which has good binning characteristics. The present invention achieves the above-mentioned objective by a light emitting device which is provided with a blue semiconductor light emitting element and a wavelength conversion member. The wavelength conversion member contains a phosphor (Y) which is represented by general formula (Y1) and has a peak wavelength of from 540 nm to 570 nm (inclusive) in the emission wavelength spectrum excited at 450 nm and a phosphor (G) which is represented by general formula (G1) and has a peak wavelength of from 520 nm to 540 nm (inclusive) in the emission wavelength spectrum excited at 450 nm. (Y, Ce, Tb, Lu)x(Ga, Sc, Al)yOz (Y1) (x = 3, 4.5 <= y <= 5.5, 10.8 <= z <= 13.4) (Y, Ce, Tb, Lu)x(Ga, Sc, Al)yOz (G1) (x = 3, 4.5 <= y <= 5.5, 10.8 <= z <= 13.4)</p> |
