A light emitting device includes first to third semiconductor laser elements. Each of the semiconductor laser elements includes at least two emitters, and configured to emit red-color light, green-color light, or blue-color light. The mount member includes first to third conduction parts, each including a plurality of metal films including mounting regions that are aligned in a predetermined direction. The first to third semiconductor laser elements are respectively mounted on the first to third conduction parts of the mount member in a junction-down configuration.
