Abstract: A light-emitting device includes semiconductor laser elements including first color-light-emitting laser elements that emit red light, arrayed in a matrix of M rows and N columns (where M≥2 and N≥3). The first color-light-emitting laser elements include two or more first semiconductor laser elements each having an emission peak wavelength of smaller than 647 nm±2 nm, two or more second semiconductor laser elements each having an emission peak wavelength of smaller than 643 nm±2 nm, and two or more third semiconductor laser elements each having an emission peak wavelength of smaller than 639 nm±2 nm. In the M rows and the N columns, in whole or in part, a semiconductor laser element other than the two or more first semiconductor laser elements is adjacent to any one of the two or more first semiconductor laser elements.

Abstract: A light-emitting device includes first and second light-emitting elements, first and second support members, first and second protective elements, a first wiring with one end bonded to the first light-emitting element or the first support member, a second wiring with one end bonded to the first light-emitting element or the first support member and the other end bonded to the second light-emitting element or the second support member, a third wiring with one end bonded to the first protective element or the first support member and the other of end bonded to the second protective element or the second support member; and a fourth wiring with one end bonded to the first protective element or the first support member. The first and second light-emitting elements and the first and second protective elements are aligned. The third and fourth wiring do not pass directly above the first and second light-emitting elements.
