A light-emitting device includes a first light emitter and a second light emitter. A first drive current through the first light emitter and a second drive current through the second light emitter flow in opposite directions. A period in which the first drive current flows and a period in which the second drive current flows at least partially overlap each other. This structure causes the phase of an electromagnetic wave induced by the first drive current to be opposite to the phase of an electromagnetic wave induced by the second drive current, thus allowing the electromagnetic waves to at least partially cancel each other and reducing electromagnetic interference.
