Abstract
The present invention discloses a light emitting element including a carrier, at least one light emitting chip, an adhesive and a first encapsulated layer. The light emitting chip is fixed onto the carrier by the adhesive, and most of the carrier and adhesive are made of a light absorbing material, so that the external luminescence quantum efficiency of the light emitting element is poor. The invention adopts a first encapsulated layer disposed on the carrier to cover the light absorbing material including the adhesive or carrier, so as to reduce the light absorption and improve the external luminescence quantum efficiency of the light emitting element.
