In a light-emitting element in which an n-type layer of a Group III nitride compound semiconductor, a light-emitting layer of a Group III nitride compound semiconductor and a p-type layer of a Group III nitride compound semiconductor are laminated successively on a substrate, a semiconductor layer of Zn_xCd_1-xS_ySe_1-y (0x1, 0y1) which receives a part of blue light from the light-emitting layer to thereby emit yellow light, is interposed between the n-type Group III nitride compound semiconductor layer and the light-emitting layer.
