Abstract: It is an object of the present invention to provide a light emitting device which is less affected by a malfunction caused in a light emitting element. It is another object of the invention to provide a light emitting device in which light emitting elements are connected in series. As to a light emitting device of the invention, groups of circuits each having a light emitting element and a limiter are connected in parallel. Here, a light emitting element and a limiter are connected in series. The number of the circuits may be at least two or more. Further, each circuit group includes at least one light emitting element.
