Abstract
A light emission device includes a plurality of semiconductor light emitting elements and a supporting substrate on which the plurality of semiconductor light emitting elements are flip-chip mounted. Each of the plurality of semiconductor light emitting elements has a substantially rectangular shape which has a first side and a second side different from the first side. Light emitted from a first element end face on the first side is stronger than light emitted from a second element end face on the second side. Each first side of each of the plurality of semiconductor light emitting elements faces each other substantially in parallel.
