PROBLEM TO BE SOLVED: To provide a light emitting element which can highly efficiently emit light by utilizing band-end emission. SOLUTION: A light emitting element is constituted by laminating a compound semiconductor containing at least two layers having different band gaps and expressed by a general expression of Inx Gay Alz N (where, x+y+z=1, 0<=x<=1, 0<=y<=1, and 0<=z<=1) upon a sapphire substrate. The angle between the surface and C-plane of the sapphire substrate is adjusted to 5 deg. so that band end emission can be utilized. |
