Abstract
A light emitting device includes a light emitting element having a light emitting surface from which the light emitting element is configured to emit a first light having a first peak wavelength. A light transform layer is provided on the light emitting surface to transform the first light to a second light having a second peak wavelength longer than the first peak wavelength. A light-transmissive layer is provided on the light transform layer and includes a first surface that has a substantially flat shape and that is opposite to the light emitting surface and a second surface connected to the first surface and having a curved shape to surround the light emitting element. A reflecting film is provided between the light transform layer and the light-transmissive layer to extend along the first surface and the second surface so as to reflect the first light and to transmit the second light.
