A stacked body includes a long side and a short side in a top view. The long side extends in a first direction. The short side extends in a second direction orthogonal to the first direction. The short side is shorter than the long side. A light emission peak wavelength of a first active layer is different from a light emission peak wavelength of a second active layer. A first n-type layer includes a first n-side contact portion contacting a first electrode. A second n-type layer includes a second n-side contact portion contacting a second electrode.
